In Biology, I was told, you will almost not be able to find a professor that does not have a Macbook. And as soon as they have enough money, students and scientific staff will follow.
But also in my own field, mathematics, I have seen lots of highly respected professors with Macbooks.
Now, I have never worked with a Macbook myself, but I have helped out colleagues with problems a few times and I have really have not encountered any advantages over a regular and half as expensive Windows laptop, or an even cheaper Linux laptop. Those that I know good enough to question their choice of laptop confirm exactly my suspicion, saying they thought it was pretty/everyone in their lab had one, or swear by it but never had a different laptop.
Is there something I am missing about Macs? Maybe some recent convert out there? If not, why are academics so keen on status symbols? Isn't academia the one place where content should count, not looks, or even worse, depiction of wealth?
EDIT: while I agree that this question is prone to flame wars and the question about mac vs. anything else is also not really new, I DID want to know about the specific situation for scientists and the two answers so far are exactly of the kind that I wished when I was posting the question. Now of course mentioning that Macs might(! "if they..") be regarded as status symbols attracts attention to my question ;)
