Tough call. Being as the new HTC has the internal battery and no SD card slot, that would kill it for me too, with HTC. Having said that, the other android options don't excite me, either. I'm looking towards either a BB 10 device in 2013; or (more preferably), ditching the "smartphone" entirely and go with a basic phone w/texting and an iPad. Methinks the smartphone as we know it is on the way out. For me, a single device such as an AIO device just doesn't cut it for my combined mobile needs. YMMV.
I wish you the best in your quest, bro.
