@tjcaustin: Kudos for bravery and skill in transplanting Novatouch stems to a HHKB. I need to get a lot more surgical practice on lesser boards before attempting such a feat.
In the meantime, I am readying my new Kul ES-87 with mx clears for sale (I very much like the quality and features of the Kul, but I don't like mx clears), and having fun with my CM Novatouch.
It is interesting how the sound and feel of the Novatouch changes with different keycaps and with or without O-rings. Right now, I've installed another dye-sub thick PBT set. This one is from geek_feng: white alphas with blue legends, blue mods with black legends, white arrow keys with black legends, and the right control replaced with a light gray menu key with a blue legend. These caps fit much better than the loose-fitting ones from Imsto, and the board looks, sounds, and feels great.
My only remaining quibble with the CM Novatouch is the Fn key, which is fixed and cannot readily be reprogrammed or remapped. In contrast, the Kul has a handy DIP switch setting for changing the Fn key to menu, which can then be remapped using remapping software. With the Novatouch, I remapped right control as Fn; I can then map Fn to have various functions to my liking, but the board ends up with the original Fn key as a dead key. I hope that CM will take note of this and perhaps incorporate DIP switches into their next refresh of the Novatouch, or just leave out a Fn key and have a Menu key that could then be remapped using remapping software.
Other than the Fn key issue, I am liking the CM Novatouch more and more. To me, it does not sound or feel like any of my other Topre-switch keyboards (including my RF 87u 55g, RF 87u 45g, Leopold FC660C, or HHKB Pro 2), but it has a unique sound and feel of its own, which can be modulated by installing different keycaps with or without various types of O-rings. I definitely like the CM Novatouch better than any Cherry mx keyboard I have tried. It provides the unmatched tactile feedback of a light Topre switch with the ability to accommodate Cherry mx keycaps.
I will soon be selling all my Cherry mx boards, but keeping the Novatouch as the new home for my best Cherry mx keycaps. I've tried mx brown, blue, vintage black, green, and clear, and I have not liked any of them. I might still give reds and contemporary blacks a try before giving up on Cherry mx switches altogether. However, there is no question about liking Topre switches, including those in the CM Novatouch.
