DRM can be so annoying!

I like STEAM. I think its a great service. It has DRM that is not annoying, and works very well. I can install it on as many computers as I wish, but only run it on one at a time. I think that's a very good deal, because how often do you run a game on two computers at the same time? Not very often I bet. So, if STEAM is good DRM that stops people from stealing stuff, why don't other companies, like EA, stop using their crazy DRM system? I would totally buy that new batman game off of STEAM if it did not have that crazy DRM. Same for Far Cry 2 and the Crysis games. I don't want to have to deal with the other DRM, because I think the STEAM DRM works well enough. I mean, whats the point? You can't steal games from STEAM anyways.
