Is Google the future of eBooks?

As I've mentioned, I love my Kindle (I really do), but I'm not crazy in love with the Kindle store. I went to download a book the other day, and and it seriously took me like fifteen minutes to pull the trigger. The problem wasn't the $9.99 I was paying -- I would have gladly paid more for a physical copy. The problem was that if I pay ten bucks for something I want it to me be mine. I don't want it to be locked in some device that I may or may not still have in two years' time. And I don't want to be forced to buy another Kindle when it's time to upgrade because I've got hundreds of dollars worth of books tied to my Amazon account. Granted, Amazon eases the pain by offering kindle software for PCs and smartphones, so it's not like if the thing breaks I'm out of options. Still, it's the principle of the thing...
