Hardware wise I'm pretty impressed with the One. Looks like a very cool looking phone. The camera looks very interesting, looking forward to reading some reveiws on it.
Software looks good as well, lots of of bells and whistles. But it seems there were a lot broad strokes during the release event so I'm cautiously optimistic
But saying that, my GF is due for an upgrade and she's a big HTC fan so I'm going to try and convince her to pick this bad boy up.
