"How can you buy an XBox after all the buggy Windows crap Microsoft has thrown at us?"

Answer:

"One has nothing to do with the other"
Bad analogy, microsoft has released quality products year after year with free updates to newfound bugs everyday.

On the other hand, Sony attempts to load malicious spyware copy protection onto your machine. (and if you try to tell me its only possible because of windows, I'll laugh because the same thing could be written for OSX) Bad Bad Sony! When I bought a 65" sony TV, the HDTV "unit" went bad, and sony refused to replace it because it only screwed up on ~50% of the channels.

I could go on and on about the crappiness of Sony products and why they are a POS corporation, but its all ancedotal.
I'm wonder if any of these people (http://www.ps2settlement.com/) will be buying PS3's?
