Still shooting for a release before this winter, in the last phases of testing...ya droid battery.. I have to carry 2 with me. ha.
I have an extended battery on my X2 and I can run the hell out of it! And at least you can change out the battery vs. ANY
1) Extended battery- I got the verizon one, xtra 400ma and virtually un-noticeable.
2) Minor power management adjustments (like not using animated clock ..., keeping backlight on low, etc)
3) One of these: http://www.igo.com/mobile-devices/charg ... 002730001/
Those three things will last you all weekend without a charge. I can make my extended battery alone last all day using my phone as my primary gps in the backcountry. I just put it on airplane mode with a toggle switch, toggle it on then check my gps position, then toggle it off again. I'm sure with just the extended battery you needn't worry about that for a day on the slopes because your phone won't spend the whole day searching for a signal like it would in the backcountry.
Glad to hear the X2 has improved battery performance.
All I can say is that I view the person who founded and grew the company as a hero, and the person that bought it and tore it down as a parasite. And I say that as an avowed capitalist.
