Other studies have been done, that showed close to 300 potential violations in the Linux kernel alone.
I went Mac three years ago.
Smart move steering clear of Linux, Apple is a US company and a technically better product too.
So to return to my question: why isn't MS specifying what is being violated? Looks to me as though they are repeating the antics of its discredited and delisted former patent troll subsidiary, SCO.
In the long run, I actually count this as good news. It hastens the collapse of the American intellectual property system, which has now become the laughingstock of the world. Good riddance!
OS X includes a LOT of open source software, even GPL software found in almost every Linux distro, which is likely subject to the same patents.
BTW, currently Linux is faster on the same box. OS X has some inefficiencies that slow it down.
