Deadly-Bagel is right - this is for the new, keyboard-less Kindle. To be certain, I contacted Amazon Customer Services about this. They responded (extremely quickly - within minutes!) to say that the new Kindle is NOT compatible with the old Kindle Keyboard covers, but that the product on this page (in any of its colours) was the one to go for. (I've now ordered one - can't wait!)
They also suggested Marware Eco-Vue for Kindle Cover, Black which is released sooner, but lacks the light. My wife has the version with the light for the Kindle Keyboard though, and it's really top notch, so personally I preferred to wait.
