I'll definitely go with the Motorola - the Xperia looks neat (btw. - it doesn't look ANYTHING like the teaser that was released by SE!? Was that for a non-Android device?) but it apparently won't be out until the first half of 2010 and it comes with Android 1.6, which seems to be much slower than 2.0
