Boxee has been free and available (out) for a few years though. And for the release of the "Box" they changed their complete UI. They don't exactly fit the typical model.

I believe software is organic and it's never truly finished, however, there needs to be a certain amount of content and sense of completeness to a version 1.0 - with the last minute changes Boxee really threw out the baby with the bathwater as they say.

And for me, with a product featuring a UI that used to be very focused on media/library presentation, not filtering articles is a pretty big omission. That would be one of the first things I'd have up and running simply as part of doing a basic alphabetic sort.
