Can you change the battery - preferably for something bigger?
I'm looking to replace my ageing HTC Desire this year but I want something that can last for four or five days between charges and that means a 3aH or better battery. I've been looking at the Samsung S3 and you can buy a 4.3aH battery for it on Amazon. It makes it bulge a bit at the back and adds some weight but the same is true for the 3aH battery in my Desire. Doesn't bother me in the slightest - I think it makes it easier to hold and also means it can prop itself up sideways on the desk for viewing videos :)
Mine's the one with a spare battery in the pocket.
