I want the physical disc version of the game simply so I can install it on any PC I want, but then again a disc will have DRM that caused damage to a PC for me before requiring a reformat. I'll choose Steam over SecuROM anyday, but I'd rather Borderlands be on Impulse without DRM. The biggest gripe I have with Steam is they don't use normal install directories, which makes installing mods or extras a total pain (GMod and Spacebuild 3 come to mind). Hold up, if I get the disc version it will be easier to download and use no-cd.SecuROM cracks, but these can be useless in online games because they detect such stuff. Guess Steam it is for me then, at least I'll be able to quickly invite friends to a game, the only feature Steam keeps enticing me with.
By the way I was getting ready to make a post asking if Borderland is coming to Impulse.
