I am tinkering with the idea of buying one of the dual core Intel Atom + Nvidia ION mini-desktops (e.g. Acer Aspire Revo - here)

Intended usage:
* power 1080p 46" LCD TV in the living room with:
- XBMC
- skype (ideally as high resolution as possible)
- alternatively Ekiga for high quality VCs

XBMC apparently runs fine on the ION architecture and my question is whether anyone has tested Ubuntu + Skype on one of these devices and (subject to a decent webcam) what sort of video quality they get on their video conferences?
