I have the box already since their release with me and I can assure you, it is getting better.
2 days ago the latest update has been released, with the most major bugs have been eradicated.
Anyone who follows a little the English Boxee Forum, noted as the Boxee team is striving to find a solution for all problems. Nearly a month has passed and it got out already 2 updates that have eliminated some bugs. The next update is still announced for later this year.
As mentioned in other reviews, the box is an omnivore. I do not have format found that could not be played. If anything does not go, you can send a sample and you are looking for a solution to the developers.
Apps for us German unfortunately there is hardly. But if one is mainly focused on local content not disappointed.
The interface is currently only English, and information about films / series are fetched only in English from imdb.com. For me, this is fortunately not a big problem.
The remote control is not perfect, but okay. Grey lettering on black keys was not the best idea of D-Link. Normally, I need the keyboard rarely. Most of the time one uses the box from the front of the remote control, on which there are only the most essential buttons. These can be for my taste sensing something bad.
On the whole, I'm very pleased with the box. The compatible format variety and the presentation of my films / series combined with the low cost device, is unequaled in competing media players.
Furthermore, I am confident that the box continues to develop for the better.
ps
I have no problems with the fan, which is very quiet with me.
