It is easy to tell people "if you don't like it return it for a full refund" when most of their customers are "stuck" with apple because of all the money wasted in the app store.

I have workmates that would have changed to the N900 a few months ago, but never did because they have 100's of dollars invested in apps and games.

So if you bought an iPhone4 and you are not happy with it, what are you going to do? Go back to the 3Gs? Or just get an iPod touch so you can still use all the apps you invested on?
Either way most Apple customers are stuck.
