well you can say the XBL in general with XBLA... demos, videos, tv shows movies, the compatibility for online gaming with more and more PC games with windows vista... , the simplicity of navigation.... the compatibility with msn which allows me to talk to my parents at 4000 miles away while playing GOW with no extra cost..... visio conference possibility.... great controller.... which doesn't give me blisters and thumb cramps after 3 hours of gameplay like the PS controller does (to me).... great connectivity for monitors and TV of all kind... as well as sound.... the fact that almost everybody has a headset to play online make it more friendly and great to create clans and stuff.... that's it for now
@El d for the monitor compare to HDTV you shouldn't have any difference if both products are of same quality... meaning pitch, contrast ratio, refreshing rate etc....
for the sound I guess you have a mini jack connection for you PC speakers... well you don't have a jack directly on the XBox but you can find a RCA to jack at most electronic retailers for a couple bucks.... and if you have a any shelf system or receiver amplifier or anything like that close to your XB you can usually plug the RCA connectors on the auxiliary input....
