As I said, I'm not really bothered whether it's mechanical or not - I don't really see them as much, if at all, better (beyond the really ropey domes) so I'm fine with dome, scissor, mech, capacitive...
... well, maybe not ALPS or buckling spring.
I just want a tenkeyless with dedicated media controls. Wired or wireless is also fine, but I'd prefer wired.
