I love the removable plastic back. Lets me change the battery, sim or sd card in a snap. Also I've used my S3 for a couple of years now, and dropped it a bunch of times, including on concrete, and there is barely any damage. I don't use a case.

I find the lack of SIM tray annoying. To swap SIMs I have to remove the back, remove the battery, remove the SD card, and then I can finally get to the SIM. Then I have to be careful because SIM slots can break. Lame.
