bitstream, just curious what the defect rate is so far on your side? had my HDX for about a year, then it died on me when I tried to swap out the internal HD. (changed the drive then it refused to boot up after that, with or without a drive installed. Red LED doesn't turn blue anymore and no video output)
Had to send the main PCB back to China, and looking at their forums, seems that I'm not alone in this and looks to be a fairly common problem.
Loved the HDX (YAMJ with AEON is great), wish it hadn't died so soon. Switched to an HTPC (ASRock Ion 330 HT, just a slightly bigger footprint than the HDX), but to be honest, I actually miss the simplicity of the HDX. HD files on Xbmc isn't that great (no way for 1080p, have to use another player), and since I barely use the machine for anything else than playing media files.
