Hi, I have QuickFire TK with Cherry MX green switches (limited edition) and absolutely love it. The concept of TKL keyboard with full numerical block and functional key layout as normal keyboard is ingenious idea. After some time of using it, I would like to suggest following : - making QuickFire TK with Cherry MX clear switches - I would definitely buy this one, even Cherry MX browns are too soft for me. - another row of functional keys (F13 - F24) - those were standard on some older german keyboards and I think they should be natively supported in all operating systems. It would be great to have another row of functional keys freely assignable in various applications (Programming IDE, Photoshop, Maya, ...) - that would be great. Keep doing great stuff!
