Yes. The original iPhone was: Firs, a big wow. Then a longer series of disappointments over the next few months. I remember I didn't buy the first iPhone because you could not write apps for it for the first 9 months or so (Just with JavaScript or a hacked version of XCode). And it was slow and could not do many things that other phones could do at that time.

Bought an Android soon after and so far, I have stayed. But that might change, because of the different privacy policies of the two companies.
