Yes, you can say that hisense999 about google and android, but look at its competitors on that graph on opposite side, do you want to stay with Apple, Microsoft or RIM instead, that's the alternative, and that's a key difference between OS and proprietary. With proprietary you pay upfront, and having had a Palm and Windows machine, I can say clearly they are made far inferior than Android. iPhones are different, I still they they are better designed since Apple has full control over their OS and hardware; there are glitches in Android that will confuse newbies. Google so far has made great wealth purely from advertising, not from the consumer or even from the developers themselves so that's all we should care about.
If the future see's google turning into Apple, then we go to were the resistance and cost is cheaper while still giving us the product we want or need; with OS I don't have to use the google apps included with Android, but right now they are far better than competitors: such as language translator, text to speech, etc., and all free.
