Yeah, it's that 'once configured' bit that's the kicker
I tried ubuntu earlier this year. I couldn't figure out how to:
a) Play MP3s
b) Play DVDs
c) Output a signal to my TV
d) Get the screen resolution higher than 1024x768
I'm sure these things are possible, but despite searching through the builtin help, nothing was making itself clear. I gave up, as those are four core things I like my computer to do.
My mac did all of the above right off the bat. I'm particularly impressed with the way it handles the TV - when you plug an external display in, it auto configures and then pops a box up to choose a resolution if you want a different one. And you could select a
PAL widescreen res - shock fucking horror! And it remembered the settings for next time! I couldn't even get XP to pull off this trick.
