I think the most effective DRM systems are those on consoles like the Xbox and devices like the iphone/ipad. In other words when you have a "Don't run by default" policy. Because here you can actually block binaries from running on an un jailbroken device. As soon as you allow execution of user specified code it's game over for DRM.
This present a sort of problem in that there is still a need for computers which can run software that wasn't bought through some particular channel such as an app store, therefor there are still computers that can run pirate content.
I have a bunch of games on Steam, I have no idea which ones use DRM but I'd wager strongly that every single one of them is available DRM-free on a torrent website.
Speaking personally the main incentive not to pirate games is the Steam sales and humble bundles which give me games so cheap that I'd really feel like a bit of an idiot jumping through whatever hoops in order to get the games for free.
