I've got one and as far as I'm concerned it's _the_ best looking GUI and interactive system for Freeview. You can set it to record in the background even if you're playing games, the system's turned off or you're watching a DVD.
The only thing that might bug you - no series linking (ie, recording a whole series) and that it only supports DVB-T, and OfCom recently announced that Freeview-HD will be in DVB-T2 (or something - point its, the hardware won't support OfCom's format choice).
Good point though - whatever you record, can be exported to the XMB and from there onto USB drive and watched on your PC ;-)
