I can't stand the small screens. I'll either get something cheap with fm radio or the biggest screened Blackberry there is.
I think this is a healthy attitude. I own an iPhone GS but in a few days, I will get myself the Nokia 1661 - Its is small; cheap and has no extras.
My personal reasons to ditch the iPhone (after three years):
1. Data contracts are expensive
2. Due to the small screen, I hold the thing to close to my eyes, which is actually a bad thing.
3. Apple is way too protective about it´s platform and the Jailbreak comunity is not what I expected it to be.
4. My iPhone already has cracks in the back and dust behind the glass, despite the fact that I have bought the GS just about a year ago. Apple Headphones always break on me too.
5. I really shouldn`t twitter, or anwer personal E-Mail, or shop at Ebay at work (and some other occasions).
