Query: Great...if it worked

Doesn't work on my computer! I'm not running anything exotic at all - a Dell Inspiron laptop with XP. I spent a good two hours with Microsoft Tech Support trying to get it to work; they installed several drivers, got all up in my computer, and... it still doesn't work. I bought this from Amazon, but Microsoft is honoring its warranty and sending me another one. I'll update this review next week after that keyboard arrives if it changes anything.I should mention that the thing *seems* really comfortable...
