you should probably read the claims from MS, and read about the ridiculous pattens that they've had to hide for years from the linux community, and then read the response by BnN before you post responses like this. It makes it clear you haven't ready any of those things and are just blowing hot air.
BnN has legitimate claims that Microsoft's pattens are BS and are not infringed upon in any way by the Nook. They also make a strong argument that MS's only goal is to shut down android at all costs by trying to charge licencing fees for their laughable pattens that are higher than the licence cost of windows 7. Check out Groklaw (http://www.groklaw.net/article.php?story=20110427052238659) and you can read about all of this. Microsofts only hope of winning is that BnN goes bankrupt. I would say that it's in google's interest to make sure that doesn't happen. Google can stop Microsofts push against android by invalidating any claims of "infringement" in one fail swoop. And if MS looses this, they should prepare themselves for a long ride in the back seat of the mobile computing future.
I doubt that you'll bother, but if you read on in the comments you'll notice how many people can give you exact software systems that used all of the features in each of these pattens well before 1992, which is prior art. Basically if BnN doesn't go bankrupt and can see this through.. not only will MS be stopped in their tracks and be forced to compete on the merits of their product (lol) but they're going to loose all of those pattens to prior art as well.
Personally, I hope BnN jams their foot up MS's back side.
