I have also re-discovered the Xbox. I had one soft-modded previously, but sold it, and bought a new one recently. Crystal version, chipped and with a really big hard-drive. It also starts directly into XBMC.
So now, one of my new hobbies is to buy cheap second-hand Xbox games (it's not like you can buy Xbox games at retail anymore) and install them to the Xbox. I have also bought component cables, and have activated NTSC/480p/720p (it's a PAL xbox originally). Not all, but many PAL Xbox games support this.
And I love it. Playing from the couch, loading and running games from the XBMC dashboard, without loading any discs. It's really, really nice.
Oooh fancy, I, unfortunately haven't got a mod chip or a big hard-drive so it's just XBMC and some emulators for me, which is good enough. I did however, use the completely free softmod trick, which any XBOX owner can do, providing they've got a PC and a few CDRs to hand.
Just looked at the price of 2nd hand XBOXs, you can pick them up in Game for a tenner, utter, utter bargain. Far more functional than any of my DVD players, and the 360 for playing media. It's a shame it's not powerful enough to decode proper HD files.
