Could be hardware or software, doesn't matter. I'm just curious how people rank the improvements in order of importance to them. 1. Battery life increased to 8 hours internet usage 2. Safari full screen (for more viewing area in landscape) 3. Longer screen (for bigger text in landscape) 4. LTE 5. Thinner lighter design I use my phone alot so battery life and internet experience is always really high priorities. LTE would be up higher (#2) if it was more widespread on AT&T like it will be in the next year. The thinner lighter design feels amazing to hold.
