well actually it doesnt, some of the current 360 models have hd-dvd which is pointless since its not being used anymore. also with the 360 it costs a fortune to upgrade the harddrive, i paid £40 for a 160gb harddrive for my ps3, which by the way i can also plug in an external USB hard drive of any capacity, so i can actually have so much more harddrive space then the 360. also older versions of the 360 arent even in full hd, and not to mention that they dont even use standard hdmi cables, what is up with that????
and pc's dont actually have higher res since full hd-tvs are in 1920 by 1080, which if you work out through the number of pixels actually on screen is greater than the standard 1280x1024
1920x1080 = 2073600pixels
1280x1024 = 1310720pixels
1440x900(widescreen moniter) = 129600pixels
also pcs have only got better graphics on about one game, that being crysis which to be able to play on highest everything, well you need a dam high spec PC (quad core 2.6, atleast 1gb graphics and about 2gb ram, which is way too expensive). and not a huge number of computers actually have blu-ray in them anyway...also for controls, well you can plug in a usb mouse and keyboard (wired or wireless) into the ps3, and some games on the ps3 such as UT3 let you use mouse and keyboard instead of the gamepad
