yeah that article is pretty dead on my experience too.
I have a friend I design websites with, he's the code guy I'm the design guy. He is PC and I am Mac.
At my regular job I've had to use Windows XP for the past couple of months and he just installed Panther on a mac at his work.
He loves it and now wants to buy a G4 while I am finding XP easy enough to use but just "not me". The most annoying thing about XP is that it seems as though its designed by a 15 year old. As a designer I can't be using a comp that isn't slick...just feels wrong! Its like asking a race car driver to drive around in a Ford Tempo.
That said I'd still like to have a PC at home as an A to B car. Although mostly I'd prefer to drive the Mac Bently.
