I've been an iPhone user for the last ~4 years and have, overall, been pretty satisfied with them, especially my current 4. Rather than just buy a 5, I'm interested in considering other options that might be out there, and the Samsung GS3 looks like a pretty cool phone. I've not had any experience with Android-based phones, but I'm pretty tech savvy, so I'm not worried about a steeper learning curve. I'm going to find someplace to play with one this weekend to see if I like the form factor, but I am interested in opinions of folks that live with the phone daily on usability/reliability and especially opinions relative to the iDevices. I currently have AT&T and intend to continue with them, so the opinions of any other ATT users would be doubly valued. Thanks!
