I hate to make a "This is the year of" prediction, but I think some of the casual consoles will pick up a bit of steam with the crap Microsoft, Sony and Nintendo are putting out.
Now look, I'm buying an Ouya and a lot of people like Steam but they both require online activation and many features will continue to require always-on. And Steam loves to revert to online mode, or has in my experience. I only launch it now and then to see if any new Linux stuff has appeared (Osmos showed up, whee, that's been on Linux for ages but not on Steam) and to try to finish downloading TF2, which should be an easy overnight download but not with Steam! Why, I have no ideer. I usually forget to resume the download. It has restarted itself completely once. Total shit software, complete amateur hour like a cheap cellphone game that downloads one or more gigabytes of data before you can play and doesn't resume the downloads. In fact, the initial Steam update during Steam install downloads without resume, too. Someone should call Valve and tell them it's not 1991 any more.
