This is what the Amtek T700 should have been. A device with a good performance to be a VIA, that performs very well while playing videos, a device that even when it still warm it does not get really hot like the T700 did. You can read a review about this device that I wrote a while ago here, and enjoy this wonderful video review from ViaArena.
The Amtek T770 is a UMPC with a great set of speakers, highly accurate touch screen and a crisp 7 inch screen. This video shows you all of its features.
