Are you suggesting that MS has no legitimate claims to IP used in android? It seems to me that companies wouldn't do thee deals if there was no case to answer. It's not as though (for example) Samsung was a stranger to court action, and it's a much bigger company than Microsoft.

It's also a fact that Microsoft pioneered Unix on PCs in the early 1980s, and that Xenix was the most popular Unix of its day....

"Long before Linus Torvalds was able to write anything useful in C, there was a version of Unix from Microsoft called XENIX that was based on the seventh edition and BSD 4.1 with some interesting enhancements (multiple virtual consoles accessible via Alt-F1, Alt-F2,... Alt-F10 -- later inherited by Linux, record-locking facilities for database programming, etc) and an amazing level of PC friendliness that Linus will try emulate much later by essentially replicating all major design decisions that Microsoft put into XENIX for PC but using an independent codebase." http://www.softpanorama.org/People/Torvalds/Finland_period/x...
