I think the commercials are silly, but MS is notorious for slinging mud themselves (balmer sort of has a problem opening his mouth without attacking someone- and he's very high on the MS payroll and seems to love making outrageous claims). At least with the apple commercials, it's done in a silly way- that people know are jokes. When Balmer make's rediculous claims to large audiences (often time very misleading), it is done with a sense of honesty- even if it's very much based in questionable research or just pure spin.

I've used dos/windows since the early 90s, and have since used both Mac OS X and linux for work. My next PC for the house will be a Mac- it's a fine machine and does what it does. I seem to always have to tinker with my windows machine to get things to work- and linux....well, it is a great platform for C++ development and general use. But, it's hopeless with the absence of any commercial applications:(
