Just when you thought Bill Gates was gone he's back! Microsoft wants to destroy all this Vista is bad BS, and try to show people Vista doesn't suck. How will Microsoft do it? Well Jerry Seinfeld might be able to help. I have to say I like were this is going. Especially if the commercials are as funny as the Bill Gates' Last Day skit. I hope they don't bash Apple, even though they deserve it, because I don't want this to turn into a little kid fight. I want Microsoft to be the bigger company and tell me why there product is good and I should buy it. Not Apples approach of saying the other guy is a turd some buy our product. That's what a two year old would do. And I hope Microsoft doesn't go down to there level and start the Mac bashing.

Good news for Rock Band and Guitar Hero fans. Microsoft and Sony have both confirmed that all the plastic instruments from Rock Band, Guitar Hero: World Tour, and Rock Revolution(who?) will all be compatible with each game. For example we get to use the Guitar Hero drums for Rock Band and Rock Revolution. Sony has stated that the microphones for each of these games will work with their Sing Star series. Microsoft did not say anything about the microphones being compatible with their karaoke game LIPS.
As for me I am very pleased with Microsoft and Sony for making sure the games instruments are compatible. I really don't have room for 2 sets of plastic instruments. Now I can just buy the set of instruments for GH:WT and be able to use them with Rock Band.
