After last week's massively successful Free Friday giveaway, we've decided to do it again! This week, we're giving away a Microsoft Sidewinder X4 gaming keyboard. It's Microsoft's first really awesome gaming keyboard, with anti-ghosting features comparable to much more expensive keyboards. You can't win if you don't enter though, so start by following our official Tested Twitter account, then tweet a link to any Tested story (it doesn't have to be this one, all we're asking is that you share something that we wrote that you thought was awesome with your pals). We just want to reward the people who help spread the word about Tested.
