Today we will be checking out the latest addition to Microsoft's PC gaming peripheral line - the Sidewinder X4. This keyboard is designed to be the economy model for gamers. About a year ago we reviewed the Sidewinder X6 and now we will check out its little brother. Unlike other Microsoft gaming products this keyword is entirely designed by the folks at Redmond. The Microsoft Sidewinder X4 looks like a basic keyboard with the addition of media and macro keys. The Sidewinder X4 is missing some knobs and buttons found on its bigger brother the X6 but should still has plenty of features to hold its own.
