The funny way the keycaps work on the optimus maximus make it not very nice to type on from my understanding. The application profiles I imagine are nice, but is it really a keyboard at that point?
I have one of those logitech illuminated boards, it has some pretty nice scissor switches. If you're used to heavy switches you might press them way to hard and leave your joins sore. I did that for a little while comping from my Razer Lycosa, but the Lycosa has funny feeling keys even among other rubber dome boards. That illuminated board is probably one of the better non mechs out there, but for the price you could get a mech. One nice thing is that I think the key caps feel pretty durable, I don't get the impression that they'll just rub off. It's 80 dolllars for a non mech, so the maybe the keys are dye subs or double shots? I'd check but I dunno how it handles keys being removed.
