I hate:

The camera shutter slider bulge; means the device rocks when using the keyboard if it is on a flat surface like a table

The lack of a 3x4 dial pad for entering text, and T9 text prediction

That the on screen keyboard doesnt correct your spelling (Iphone is very good at guessing the right word if your fingers accidentally press the adjacent "keys" to the one you want)

The battery lasts barely a day

Portrait mode is limited; for what most people would use a phone for (other than calls) such as texting, it's near unusable in one hand
