Bluetooth 4.0 [zipped PDF of the spec] was formally announced in April, and added a new, ultra-low-power aspect to the short-range personal-area-network technology. According to the SIG, the new 4.0 core specification should allow devices to run on coin-cell batteries for years with a new ultra-low-power duty mode."

I don't throw out my bicycle's speed and cadence sensors or my heartrate monitor when their batteries wear out -- sure, the battery may be $2 after a hefty markup, but the device it goes in is $30-70.
This just makes Bluetooth a competitor in that field, rather than needing to join the "ANT Alliance" to build anything that can communicate with the wireless sensors. As someone with the occasional hobby-project idea, I'm all for that!

With Bluetooth, you either had it or you didn't. After that, most users could give a rats rear end what the latest Bluetooth specifications are out there. If they get Bluetooth 4.0, it will be an "upgrade" when they replace their phone, buy a new car, or peripheral. Much in the same manor as cellphone camera. Meh, sure why not...

Why do people insist on looking down at those who talk to their friends that just don't happen to be proximate?
I mean, jeez! There you go, yacking away with your homies and I can't do the same 'cause mine are not beside me?
What kind of technophobe are you?

This bit from TFA links has me a bit worried. With the mobility of these devices compared to WiFi, which is relatively non-mobile, what sort of walking interference (Bluetooth vs. WiFi) can we expect from 4.0 devices?
