I can't speak to the other companies, though I know google want's "all the worlds info at your fingertips" which is a reasonably high ideal... I can speak to what Apple is doing as someone whose followed the company closely for a couple decades. Apple doesn't care whether you buy the 3.5", 4.0", 7.85", or 9.8" screen. Apple is bringing the personal computer to the 6 billion other people who weren't able to get in on…
Instead, Apple put a $50 computer in peoples hands- the iPod shuffle. Sure, it might not be as full featured as a laptop, but you have to walk before you can run. This is the type of out-of-touch-with-reality comment that tech nerds make that make people laugh at us.
Of course the reason you did this is that you know what I say is true. You just are an apple hater and can't even admit that this is what they're doing.
