2010 is a great year to be a Mac gamer.

But those games download to your Mac, and run on your Mac—so if you're Mac isn't up to the minimum specs, no game for you.

OnLive wants to change all that.

Launching today at 6pm Pacific time, the instant-play service streams live games to your Mac or PC, via a browser plug-in. You control the game as if it were running on your local machine, but in reality it's running on a powerful server machine at an OnLive data center up to 1,000 miles away. We spoke to founder and CEO Steve Perlman about the service, plus got our hands on it at E3 just yesterday. Read on to find out more.

So, you love your level 75 Human Rogue, but you just can't see to find enough time to head over to the auction house at Ironforge to get yourself that lovely coat of armor you've been coveting all this time? Fortunately for you, Blizzard has released all the juicy details about the Remote Auction House functionality of the Mobile Armory app. However, it only works for a tiny number of World of Warcraft servers because it's still in beta.
