I'm on my second galaxy phone. Had the Sprint Epic and now AT&T GS2. I'm annoyed with Samsung's bugs. Ready to try something new. Just a couple concerns. One is that I usually follow a phone of interest for months before release. This time, I really have no idea what's out there, the good, the bad, the ugly, etc. So I feel like this is an impulse purchase, and that scares me. Two, I'm used to carrying a spare battery since I am a heavy user. Is battery life really as good as they advertise it to be? Lastly, what are the cons of not having a micro sd slot? I currently have 16gb internal and 32gb sd. So I am pretty comfortable with having 64gb, but what if your phone is destroyed or something else happens to where you can't get in there and retrieve all your stuff??
