You seemed like you liked HTC before, might as well wait until April 10 to see if HTC was telling the truth. That's the new date set for the M9, same date as the S6 launch
But for anyone looking at buying a new Android phone this year, the S6 is at the top of my recommendation list, I'd tell anybody to start with that. I don't feel like the others will be as complete.
Looks great, best cpu/gpu & flash storage combo and it's all Samsung parts nothing else other than the Note 5 would get, best screen, lighter touchwiz, and for the first time ever for a Android phone best camera. Beat the 6 & 6+. Can't see LG, Sony, or anybody else checking all the boxes like that since they either can't or haven't ever done it before.
Awkward looking with one edge, side notification is kinda cool
Would pick the regular over it if you went that route though, better battery and cheaper
N6 is a two handed device at all times it's pretty much a tablet, way out of the phone/phablet category
N6 probably has better camera too. Idk, I'd pick the M8 but only because I don't like phablets. N6 in N5's footprint is easy money on the N6.
But at least you wouldn't have to worry about something like this happening to the N6

Band 12 must be LTE for your area, that's the only band the phone doesn't support for AT&T
yeah that looks about right
