Well.. iphone is like iPod. For mp3 player, there had been a lot of better mp3 players available on the market such as iRiver. But marketing and vibe of iPad of Apple had dominated the market. Nowadays, you can find many arm bands, cars, stereo system, and many more gizmos just comparable with iPod. I see that same pattern is already happening in smart phone market.
If then, what are you going to choose, iPhone vs Android?
