htc hd2 and some samsung galaxy phones are the only ones to my knowledge (limited as it is) that run 64 bit ...currently....
as aged as the htc hd2 is...
it's still a beast.
what did it run again?...
win 7 8
ubuntu
meego (if it could run meego then this device is def. something to look at..who knows ...perhaps nemo then may work...doubtful sailfish...perhaps freemantle will work when it is done...hhmmm...if meego ran on it...then mer?...possibly?...)
and as far as droid goes...I heard months and months ago that someone got lollipop to run on the hd2...
beasty is unkillable...it keeps coming back from the bloody grave...
and even though it is as old as the n900...
the hd2 is STILL a wanted and coveted device...
