I set the system up in a fairly simple matter: cable goes to my TV already. I split cable (you can get your local cable company to do this) so one goes to the TV, and one goes to the cable modem. I connected the cable modem to a wireless router (I recommend SMC's Barricade). Lastly, I plugged the Xbox into to one of the router's ports, and set the rest of my network up for wireless. Voila. Internet in the living room.I like figuring stuff out and getting stuff to work. Most other techies out there share that sort of interest as well, but how many of them have an Xbox and a fast connection at home. Very little.
Now, balance that (if you can) against the line up of games available for the Xbox (live and un-live) and it ads up to a big ass yawn compared to the new Lord of the Rings game available for the Playstation2. DROOL. [December 12 update: LOTR for Xbox is now coming soon, but the fact remains the game line up for PlayStation is at least much larger, and likely, better]
My point? Compare the experience of getting your Xbox Live mojo going compared to any other gaming platform, and it doesn't look compelling (yet?).
