TUAW has a nice roundup of posted reviews, as does Mac Rumors. The guys over at Boy Genius Reports have a great hands-on, as does Engadget — coupled with Joshua Topolsky’s excellent review of the device.
A few things have struck me as I’ve read through these reviews — that this phone feels as good as it looks, the screen really is as awesome as Steve said it is and that the box is really, really ugly.
