The battery is still the big selling point, but everything else about the device has been improved. It's faster, the screen is much better and has a much better overall feel. I use NFC heavily and was very happy to have that back, and with 32gb internal now I have plenty of app space with a 32gb microsd for media. It worked out well for us, as my wife took my og maxx and we retired her bionic (on the day of ICS rollout, lol). The radios, battery, screen, nfc and build quality sold me on this. I have had alot of android devices, and every one of them I have rooted and flashed roms but becoming more and more busy in my daily life I need a device that can keep up and doesn't need tinkering... this is that phone.
