if your just looking to stream media, get an asus o'play or a netgear eva2000 or something like that, will stream from your desktop, a USB drive, the internet, those both go for $100 each.
they just released a firmware upgrade for the netgear oen that really made it shine, plaing a lot more media files than it did before, AVI, MKV, etc, limited to 720P however, the o'play does 1080
but that would be a lot cheaper for just a media setup.
