Simply put, they feel nicer to type on and have a much greater operating lifespan than membrane-based keyboards. This is because each key has a mechanical switch with metal contacts, rather than simply being a carbon pad embedded in a big silicon sheet.
I'm sure they feel nicer, but since I'm not willing to pay up front without being sure I prefer switches and haven't seen any on display to feel for myself, it's hard to make the leap to mechanical, even though I've been looking at them for over a year now.
I've also read the lifespan/keystroke argument many times, which just makes me wonder how many keyboards people go through for that to be part of the discussion. I've been using the same Logitech keyboard for around 7 years now.
I've been plenty tempted to just buy one and find out, as most swear by them, but from the outside, it really appears to be among the most pointless of luxuries.
