Google's Free Satnav Outperforms TomTom 242
Barence writes "A real-world road test of several different satnav systems has found that the free Google Maps Navigation outperformed TomTom's premium GPS unit. PC Pro put the satnavs through four different real-world tests, covering country roads, inner-city traffic and motorway driving. The Google satnav finished the four tests more than half an hour ahead of the top of the range TomTom Go 950 Live. 'For those in rural areas or people who spend hours in their car every day, we believe the investment in a dedicated satnav device or software will still pay off,' PC Pro concludes. 'But for the recreational user, it's amazing what you can get for free.'"

This reminds me of something I've contemplated numerous times before, which is the realm of generic, multipurpose hardware. Everything is converging - GPS receivers, phones, PDAs, cameras - because it simply makes sense. There are two problems with this.
One is that there are certain physical controls and form factors that are more conducive to certain uses. For example, many phones aren't the best cameras because it's too easy to cover the lens, the "shutter" button is not in an ergonomic location, etc.
The other is that often the devices need to be used simultaneously. And I don't mean multitasking, I mean two devices visible and usable at the exact same time.
I just can't help but wonder if, as the price of components drop (like all-in-one chipsets, LCD panels, etc), if there will be a market for iPad / iPod Touch like devices that are essentially generic computing devices with integrated connectivity, GPS, camera, etc. There would be various physical form factors available - like touchscreen only, buttons on the sides, fold out keyboard, an SLR sort of design. Thus I would buy a $150 generic device and designate it as the GPS in my car. Obviously most people can't afford cellular service for every piece of hardware, so these devices would have to operate in an offline / standalone mode, like as a GPS. Or better yet they would all "tether" via bluetooth or wifi off of my actual cellular device.
Anyway I'm just wondering when or if this will happen. Obviously with companies like Apple charging a premium for a generic device (iPad / iPod Touch) that's not going to happen soon. But I'm sure there are manufactures that could produce the equivalent hardware, today, for $199.

As a techy, everyone expects me to have some all-singing device that does everything. People who use their iPhones to navigate ask me why I don't do the same (apart from not having an iPhone myself).
My justification is this: My TomTom does one job and does it extraordinarily well. Google Maps *can't* compete, I'm afraid, but is an adequate substitute if my TomTom is out of commission (hasn't happened yet except once when I left it in a car in Italy). My phone does one job and does it extraordinarily well. My watch does one job and does it extraordinarily well. My digital camera does one job and does it extraordinarily well. I see no need to have to accept inevitable compromises by throwing those functions into a single device which, if it breaks, means I lose all the functionalities.
I don't see the need for convergence at all. Yes, I carry several gadgets but they are all better at their jobs than any genericised device that claims to perform their functions. And when I'm not taking photos, I don't need a camera. When I'm not driving, I don't need a sat-nav. You get the idea.
It's easier this way, cheaper (overall, it is, because of the lifetime of each component of the products - if my TomTom breaks, I only have to buy a new sat-nav, if my phone breaks, I only have to buy a new, very basic phone), more reliable (my phone can break but I can still get to my destination, or my sat-nav can break and I can still phone someone to ask for directions) and I don't have to upgrade, install, manage a generic computer like I do for 99% of my working life. If my TomTom breaks, I moan at TomTom, not worry about whether it's because I've recently upgraded my phone. My phone is quite basic but does everything I need, so I don't need to stay on the bleeding edge. It makes phone calls and sends text messages. It *does* have a built-in camera (because it was all but impossible to find one without at the time I bought it) but I've never used it. It can go on the Internet, but I don't have it setup to do that.
In an absolute emergency, yes, I can use the additional features on these devices to perform some of their secondary functions (i.e. I have a car accident, use my phone to take a photo of the scene... it's better than nothing. I'm pretty sure my TomTom can talk to my phone but I haven't bothered to set it up). But overall, I have devices that conform to the UNIX-philosophy - do one job, and do it really well. I don't have hulking bags full of gadgets, either. My devices fit into my pockets comfortably and I'm not carrying any more than I absolutely need to. And because I buy single-purpose devices they don't need to be the advanced models, or to be high-spec, or fragile, they can be bog-standard basic units. I can upgrade a bit at a time without worrying about the other components (if I upgrade my iPhone, does my satnav app stop working?).
And when I want someone else to do the navigating, I give them the device. I can even lend it to them. And I could (theoretically) use it at the same time as being on the phone to the person I'm navigating to. And other things like that.
Convergence is for people that tolerate the mediocre and are happy to sit and "manage" another device in their life. Me? I just want to press a small amount of button on a dedicated device to make things do their job. Similarly, if someone at work suggested I put all the desktops into a single machine which did everything from routing to serving to faxing to processing to replacing the network switches and modems to running the clocks on the wall to running the phone system to producing client displays etc. I would be equally as horrified. Some functions are just better off in their own self-contained devices that attract simple support (modems, switches, routers, etc). If my TomTom hardware breaks, I send it back to TomTom. If my TomTom app breaks? Good luck getting support from either TomTom or Apple.

My Tom Tom has this ability, but it's a paid service and quite pricey for someone who doesn't do an awful lot of driving, but I did get it free for the first three months (when I was commuting a few hundred miles some days) and it was great. If they could offer this service for free (I believe they charge because it requires a data connection in the unit, but I have a data package on my phone they could hook into if they wanted to remove the cost element) it would remove the only thing Google probably does

The article is astoundingly hard to read. Apparently they took a bunch of GPS devices, gave each one to a driver, who was in a different car. They all started at the same place and time, and were told to go to the same destination. They had to follow the instructions of their device and follow the speed limit. OK. Sounds good.
But they all did this only one time. You would need to do this many times before you could start to draw conclusions from it. Sure, it is fun to play scientist and get out in the world and do some sciency fieldwork, but seriously. Anybody who has taken basic statistics ought to understand that meaningful conclusions can't be drawn from this because of the huge variance of travel times as a function of local traffic. Sure, the cars all start and end at the same spots, but they take different paths. If one path that would otherwise be the fastest is slowed down because of a car accident or an adorable family of ducks is walking on the roadside, that will skew the results for this single trial only.
It makes me sad that this sort of thing passes for research, and it makes me even sadder that people don't think critically enough to realize it is not reliable.

TomTom vs. Google? Sure... (Score:3, Insightful)
As someone that is somewhat knowledgeable about in-car navigation systems, sure, go ahead and compare some free web service to TomTom. While you are at it, compare Magellen as well. They are going to be about the same.
You can also compare most of the in-car systems (built-in and aftermarket) and see they are all about the same - mostly crap but often much better than a paper map. The displays aren't terrific and can be hard to see sometimes in direct sun. Also, the routing is debatable and the POI (Point Of Interest) listings are usually out of date, when available at all.
Yes, there may be updates, but it takes the company long enough to build the map database from source materials that it is assured to be out of date by the time the user gets it. This is very, very annoying when trying to use such systems in areas experiencing significant growth.
So now you have a uniformly negative opinion of navigation systems, right? Then compare what you have seen with a Garmin unit. Their processing path for the data gets current data out to the user much, much faster than other companies doing this. The POI database is much more usable and the UI is much better. Yeah, I carry a Garmin around with me.
So please, if you are going to compare systems, compare something real that works for the user. TomTom is cheap and pretty popular, but it doesn't have the UI or the data to really do a good job.
No, I didn't use to work for Garmin - I worked for a US-based map data vendor. And we helped a lot of people build in-car systems and were usually disappointed at some of the choices they made. But we had to remain pretty neutral.

There's many issues with your arguments. Some TomTom's offer a feature when the end user can correct errors that may pop up right on the GPS unit its self (insert POI's, correct a road if it's a one way, etc). This gets uploaded to a community database at TomTom when the unit is plugged into the PC.
As for Google Maps, they only compared it on ONE system. What about Windows Mobile, BlackBerry, or iPhones? I know google maps

But you can pair your phone to an external Bluetooth GPS unit (at least Ovi Maps lets me do so, don't know about Google). Also note that you'd normally download the maps for the region you expect to use your GPS through WiFi, and not on the road (which was the major "problem" they found with Ovi). If you remove the extra time they took to download the maps on Ovi due to sheer incompetence, it performed on par with TomTom. Slower than Google, but with the added benefit of not requiring data at all.

What? A model-T with one of those shaker flashlights taped to the engine and harvesting its vibrations should be able to power that stuff, you're talking about a fully passive receptor for the GPS and one that people can carry around in their pocket powered by a tiny battery all day long.

If the little car-socket-to-USB adapter widget is(either through severe cheapness, or through rigorous adherence to the USB spec) only delivering 500ma, a modern cellphone working hard could easily be draining the battery, or at least failing to charge.

Uh, no. 15A at 12v isn't the same as 15A at 110v.
15A at 12v is only 180 watts of power.
15A at 110v is 1650 watts of power.
However, you're correct, 180 watts is certainly far more than any cell phone uses, the GP post is clearly wrong. Cell phone batteries are typically something like a max of 1 amp hour at 3.2 volts. If the phone exceeded a 10A (conservative) at 12v draw, even in a worst case scenario where they are using an analog regulator to drop it to 5V charging current and therefore only harvesting 10A at 5V, that would mean that the phone could only run for a maximum of 6 minutes on a fully charged internal battery doing 3G. Actually it wouldn't work at all, because if you tried to draw 10 amps out of a 1 amp hour LiIon battery, it'd catch fire (or more likely, just pop a polyswitch and shut down your phone).
