El Dude -
I can answer the VGA/Monitor question: With the VGA cables, you have VGA input, but also L and R audio inputs as well, so it's a combo. So basically instead of the video input, you have VGA + enough distance on the L and R sterio inputs to hook it up.
IMO, thats one of the X360s most brilliant features. It's not only HDTV ready, but for a few bucks, you can get 720p displays for nothing. I found my X360 monitor in a trash can.
But anyways. My favorite points on the X360:
Games - by far the strongest next-gen library, but current and proposed.
Online - Every game has atleast some measure of online play, which has forced devs to think outside the box, and create some memorable online experiences.
Service - even though some have had problems with MS, I have nothing but praise on how quick I got my X360 back from them.
Demos - every XBLA game has a demo, and I'd say atleast half (and every major title) of the standard games have demos. Some demos are good, some bad, but overall, a great service.
Patches - free online patches that tend to be rather quick in terms of the content that they provide fix game-critical issues (like Oblivion).
Downloadable Content - With GTAIV having exclusive content, and all the great DLC, both free and pay-for on the X360, it's great. I loved buying Shivering Isles. A new game+ for Blue Dragon sounds great. Ect, ect.
Overall, I love my X360. I don't think I've enjoyed videogaming so much since I bought an SNES back in 1992.
