I'm sure there will be lots of "it hasn't got a removable battery/SD card slot, so I won't buy it" comments. Sure, it's not a high-end phone, but battery life has become a real issue for me (and, I expect, others).
Every new release of Android places greater demands on the phone (no surprise there for anyone who's been involved in computers for more than a few years) to the point where I really don't feel comfortable going out for the day with my Galaxy S3 unless I take a spare battery. With no option to replace the battery, 'range anxiety' would be a serious problem.
