You know, it really is possible to see product reviews in terms other than "Does the reviewer like Apple or not".
Personally, I find the iPhone interface incredibly annoying, and while I have reservations about the lock-in with AppleTV, at least it's half the price of this, and if you don't mind tinkering, will do pretty well on the media playback front.
Given that the user experience for UK-based online media is so poor, and that that's one of the main reasons you might consider spending £200 on this instead of less than £100 on something that will play most of the media you have on your network, no I don't think 55% is terribly unfair.
If you want iPlayer, for example, you'll get a far better experience from any number of Freesat receivers, some Freeview HD kit, and assorted other bits and bobs. For a large number of ordinary punters, that side of this product is really not ready for prime time, and that affected the score dramatically.
Where this excels is as a media player for content on your own network. But really, is it worth paying £200 just to get some fancy indexing options? I don't think so.
Ask yourself, if this didn't have the online media support, would you pay that price, when there are media players available for under £100 that can do as well? Would you be happy if we gave it a high rating when there's equivalent kit (and we do consider value in assigning scores) for far less?
In my opinion, the Boxee Box fails on the value for money front. And it certainly fails on the UX front as far as online content is concerned, for users in the UK.
That's why it got 55%. Not any other reason. And certainly nothing to do with speculation about whether or not I like Apple.
