I was under the impression that you could plug the 360 into a computer monitor. If so doesnt that solve the "Tv resolution is too low problem"?
You can. A 19" widescreen monitor doing 1280x1024 should look pretty good, and can be had for under £200.
I thought so too. But, why not use your PC as a gaming console then?
Because you can get an XBox 360 premium pack, extra controller and three full price games for about the same price you'd pay just for a not-quite-top-of-line videocard? Not withstanding that you still have to put up with installing 8 gigs of data onto your hard drive, copy protection systems that - best case - are a pain and - worse case - stop the game from running unless you use a pirate version, and all that sorta thing.
Don't take that away from XBox 360. Being a cheap alternative to high-end PC gaming for the more action-oriented PC-gamers is about all it has going for it ;)
