Picasa--although I think that maintaining its status as competition to iphoto is key to keeping people using picasa web albums and certainly new enhancements point towards pushing user content onto Google+

There's always been a massive price difference between the pro and standard version, $500 and free. The pro version looks like fun but it's way over priced. Cut it in half and I think a lot more would consider it. Google was mostly feeding off designers that are software challenged so they were able to keep the price high because they really didn't care if it sold or not since the focus was the free consumer version. I think they'll be in for an ugly surprise if they try to charge for Sketch Up the basic version so I doubt that's in the works. I'd expect fewer upgrades and more versions with the pricing being more distributed between the free standard version and hopefully a cheaper pro version.
