Yeah, they have allot of the newer games but what about some of the older ones. Some times I like to go back and play X-Men vs. StreetFighter, Marvel SuperHeroes, Samuri Showdown, etc; which they don't have ports for on X-Box. But it wasn't just the fighters I was conserned with. I'm mainly conserned with the shooters. How well does Area51 run on X-Box. I'm curious because I think it would be cooler to use an X-Box with some X-Box light guns than to use the cheesy looking ActLab ones. I don't think X-Box is really a viable complete alternative for a PC though now that I think about it. Because I don't think you could set up a Spinner, TrackBall, etc; on an X-Box.
I have a ton of old school and a few newer capcom and snk games on my xbox and they all run fine. Pulling off special moves is a cinch as well, I've never noticed any lag, but because most of the old school stuff seems slow by todays standards I have my xbox running them at 110-120% the speed and it does it without a problem. Although, I don't use mame at all, instead I use Kawa-x and FBA-XXX but I'm sure if mame is configured right it would work fine because the system doesn't seem to have a problem running most stuff.
Thanks Byrdo maybe I'll try seeing if I can speed them up on my PC. Oh and it's good to finally see you over here on these boards!! 
there is no point in getting an xbox for shooters as its only got two native xbox shooters one sucks and the other you can get on pc. and stuff like Area 51 (IE: CHD games) simply will not run on an xbox, and that means you miss out on all the awesomeness of zinc games as wel, and playstation emulation etc... on the other hand the xbox emulates the gb, gba, gbc, gg, genesis, sms, snes, nes, all those old consoles perfectly, so depending on just how much you want to/ need to emulate, make your choice that way.
but in my case i had originally thought of getting an xbox to run my mame cab, things it had going for it were, price, house of the dead 3, guilty gear xx, dead or alive, and it could sort of run stepmania....but then i got HOTD1, 2 and 3 on PC ( 3 looks better on pc too) and Guilty Gear XX, and stepmania can support near unlimited songs on the pc as opposed to about 200-300 on the xbox and so my 1000+ list blew that limit...so i got a TV and a PC, cost less than the (supped-up) xbox i was planning on getting, i was sure i could run all the games i wanted to, had a much higher compatibility rate, greater options (playstation emu for ex) and have not regretted my desicion one bit.
and for all the "other" console games i may want/need i have a PS2 with a 180 gig HHD
