Trust me when I say the 360 isnt free from compatibility issues, anyone who has played one knows this. Many 360 games have inexcusable issues for console games.
Oh and most PC gamers have full 5.1 or 7.1 surround sound systems with sub on thier computers. Any current GFX chipset capable of playing Oblivion also has DVI outputs or component outputs meaning they can still play the game on their big ass HDTV if they have one. Oh and thanks for mentioning that PC gamers will install the game thus giving quicker load times.
I love the responses from console gamers. They think just because their PC is outdated as hell that PC gamers computers must be also. Just to be clear, PC gamers will not have to upgrade for Oblivion as they are a PC gamer meaning their PC is built and used for games.

I agree that the 360 has issues, and I have a gaming computer. But I would far rather use the 360. Mainly because I don't want the loud computer moved to hook up to my tv. My home theatre kicks the ass out of my 5.1 computer system and I don't have to boot an OS to play the game
Sure it'll load faster but the ease of use makes up for it. Besides the xbox 360 cost me $455 a GFX card that would play it better than my 360 would cost more than the system.... work that out
