ok lets get a little more serious and drop the mac vs pc bullshit.

ask the question instead, what machine will suit the person better? what is their temperament like? what do they want to get from it?

then you can decide if they want a Mac, a PC running Windows, a PC running Linux or something totally different like a new mountain bike.

asking us ain't gonna help. we've all got these prejudices in the eternal holy war of 'what I like is better than what they like' and you won't get the answer of what is best for the person.
