Looks pointless and decidedly lacklustre for high definition playback, to me...
That's a very expensive product for something that hasn't been tested with a high definition source. For that sort of money I'd expect something that can handle HD-DVD or Bluray in the future with ease.
I really question the emphasis of the review - the omission of firewire is far more serious than the addition of two PS/2 ports (cost of a USB to PS/2 adaptor : a tenner). Compared to the 100HA (which is itself expensive) it's terribly unattractive.
What, exactly, is the point of a product which can only watch TV/DVDs (as it is unusable for games and flawed at web browsing).? For 850 quid you can purchase Toshiba's bleeding edge 1080p HD-DVD player *and* an embedded DVR. The HD-DVD player will play CDs too, which XP Media Centre won't...
