Gaikai beta goes live, brings Mass Effect 2, Dead Space 2, Sims 3 and Second Life demos to your browser window

Remember Gaikai, the cloud computing service that lets you demo video games in your browser window without downloading a thing? It's live, meaning it's no longer just us tech journalists that get to give it a thorough try. Provided you have a blazing fast internet connection and both Flash and Java installed, four streaming game demos are a just a click (and possibly a survey, or a short wait) away, including three EA titles (Mass Effect 2, Dead Space 2, The Sims 3) and Second Life. As we discovered in our initial hands-on, it's not a flawless experience even with a fantastic internet connection, but it's not meant to be -- the entire point is to allow you to adequately sample a game right before making a purchase decision. It's also a free taste of the future, and you don't see those every day.
