Re: Not entirely true
The TiVo box is actually much nicer than the V+ box from a UI point-of-view. It's much faster and more responsive, navigation is easier (fewer button presses to get where you want to go, dedicated Home, Guide, and Recorded Shows buttons), and it's got lots of little bits of polish (if you scroll back in the TV guide, you can select programs and it will load them from iPlayer/4OD/etc, is one example of that polish).
Features like watchlists are good too - just add a watchlist to "Record anything directed by David Lean" and it will.
When I got it it was also £3 a month cheaper than V+ (although it cost me £50 upfront).
However, it won't do streaming, DLNA, or anything cool like that.
