I went with the Logitech spectrum 910. Really nice keyboard. It's replacing a rosewill cherry mx keys. Also nice and solid though a bit to noisy. It's going to take awhile to get into this Logitech. Also includes a smart phone interface. The pull out slot simply holds the phone. You download an app that somehow ties into the game. Would have been nice to offer charging but it will be useful for watching keynote speeches while working. Eventually I'll figure something out to use with Mame and post it here.
