So what do you think it is? (if you don't know.. http://www.ubuntu.com ). As of right now, the countdown timer shows about 5hrs, 45min. Canonical apparently kept this one a pretty closely guarded secret.... as even some of the folks I know who do some dev work, have no idea. Most seem to be thinking a tablet/phone OS, probably based on Unity (since touchscreens was part of the goal of Unity anyway). Seems it will be a tough market to break into. That's obvious when you see how Microsoft has completely flopped it's tablet OS launch. I have a feeling Canonical will do better than that, but I guess we'll have to see.
