This is the exact model I'm typing on now, and have a Das Keyboard for Mac at home (because I couldn't find anything less pretentious-sounding with Mac keys). The thing I prefer with this keyboard over the Mac standard, and similar low-profile keyboards, is the lack of 'mushiness' when you hit a key. Did I hit that key with the right amount of pressure? Did it really register, or just kinda mush into place?
This is literally never an issue with mechanical keyboards, because no guesswork is required. Once you're used to the activation points and tactile feedback, you should find that you're using less pressure and getting greater accuracy with your typing.
Unicomp's Spacesaver M is a buckling spring keyboard with Mac keys. I like it a bit more than the Das, and it's both cheaper and seems to be built better. (It's pretty ugly, though.)

At least, that's how it worked for me.
