I don't think so, the computer will see and treat it as a PS2 device. Though the keyboards internals are probably designed around USB if thats the case so err.. not sure how that works out.
Yep, but they're cherry MX Blacks. Totally linear and no sound. Its just one smooth push, no bump, no increase in force, nothing. The key press is registered about half way down too, which is weird at first, if you rest your fingers on the keys a little too heavily it registers, but that didn't take long to get used to.
I like only having barely tap a key to get a a keypress registered, I don't have to concentrate and fully push each key in. In the end it sounds pretty similar to a normal keyboard because you end up hitting the key on the steel backplate. I love this keyboard though, it's built very well. I could kill someone with this, it's damn heavy for a keyboard. You could easily knock someone out if you hit them over the head
The keyboard would likely survive too
