I agree that this is unlikely to make it as a mainstream product (they can't meet demand even as a niche product) but that's not its target audience anyway.
Key phrase: bit-torrent download client.
Tells you what the target audience is, right?
That said, there is mainstream potential here; it supports pretty much any video format at up to 1080p.
A friend of mine has a Canon HD camcorder and his biggest problem is what to do with the videos; they only play on or via PC. (And he's a Mac-fan; Apple TV won't do it and he doubts a Mac Mini could even if he swallowed the price.)
I've suggested burning the files to DVD and playing them on a 360, but that's a $300 solution. The A100 comes in at $180. He's looking at it.
Here's another review of it:
