That does look pretty nice.

I think I settled on the iPad for now. I can create a fully customizable layout which will nicely interface with the HTPC and does iTunes well (as well as all other HA). The only real disadvantage is the lack of hard buttons, but that is largely mitigated by the customization of buttons and their relatively size based on priority. It is mounted on my chair, angled towards me, and acts almost as a "zero" handed remote for the most part. Some issues, but nothing too major and if seems to be fitting all of my needs.
