Regarding the patch, I see that it essentially kills whatever "bad"

The Microsoft/Mindcraft/ZDNet benchmarks:
     a) prove Linux is faster than you will ever, ever need.
     b) are a fantasy and shouldn't affect your purchase decision.
Read why and decide for yourself at http://cs.alfred.edu/~lansdoct/mstest.html
See http://www.heise.de/ct/english//99/13/186-1/ for more applicable tests.
