I picked up a HTC desire last week and managed to do some interesting comparisons with my itouch.
The iTouch is more musical (as expected) and has the edge when it comes to movie audio, however films looked SO much better on the (slightly larger) higher res AMOLED screen of the Desire. Skin tones were perhaps a shade more natural on the itouch, but all other colours where so much more impressive on HTC's device. They really pop! The extra resolution and greatly improved contrast ratio created a depth of field that the itouch could only dream about
The catch! Well, the Desire's audio seemed to be very slightly out of sync with the video. Hopefully this will be rectified quickly!
