it might not be any faster than the droid (which is debatable) but it certainly won't be any slower.
the more advanced processors we can get on android phones the better i say. then maybe we can finally get some devs to write programs that really take advantage of the extra power.
personally, if it comes out and is as thin as the HD2, looks about as good as it, and gives me similar battery performance [similar to the droid], i'll probably get it.
but not because i'm unhappy with the droid, but because i have a gadget addiction
