I currently have the GN2 and am looking to upgrade to the 5, but have the same reservations as everyone else. I travel alot without always easy access to charging ports, so I've always used the (beast) Hyperion extended battery with customized back to support heavy usage while traveling. (It turns the phone into a heavy ton brick, but works great.) I'm a little reluctant about the non-removable battery and SD, but realize that this seems to be the new wave of the future for all tech devices. If I upgrade to the 5, I'm looking at this option for the device and wondered if you have any other thoughts, experience, or suggestions for extended battery cases for the GN5?
