Iphone is a good choice but i prefer HTC it is easy to use. What I hate about Iphone is you can't pair with other bluetooth device other than apple. Although there is a way, but you have to jailbreak to or buy application to fully used your iphone.
I was about to say the exact same things but I decided to read over the replies so far, beyond the "Iphone" replies. I think the average user that doesn't want anything more than the CORE features of their device or any kind of custom anything will pick iphone, also those that are driven by the crowd and think that more £/$ equals better but the rest of us that know the restrictions in place with apple products and that we are paying triple the price for two times less power and often enough even less features when buying an iphone or ipad. I won't continue to get further into a debate but I agree with the above that is quoted and then added a little for all you other readers =] When I buy something I want to ability to customize my experience with it at will and be able to fix parts if they break without paying more than the default cost of the product I do believe if Apple products were more competitively priced my opinions might differ in areas but ultimately, you get less than when you side with an Android (equivelant) device.
If you are comparing HTC and iPhone then it is iPhone...However if you compare iPhone and Samsung then it will be Samsung for sure.......!!
