What's up!
I prefer using a trackpoint for all mouse usage. What are you're favorite keyboards featuring a trackpoint(not including laptop keyboards)? Also I'd like to curate a list of all known non-laptop trackpoint keyboards so any you know of would be greatly appreciated!
Thanks!

I've actually written a page on this topic ("TrackPoint, pointing stick stick and UltraNav keyboards" topic on my website), so feel free to read to get started. As a summary, 'true' TrackPoint keyboards include:xenophile wrote: ↑03 Oct 2021, 20:44What's up!

My favourite is probably the Model M4-1. IMO, it's a great all-around portable, quiet and tactile TrackPoint keyboard. I use InterAccel to mitigate the speed issues with TrackPoint II. Followed by the 5576-C01 for sheer coolness.

You're welcome! If you're referring to the buckling rubber sleeve switch Lexmark used on many mid '90s ThinkPad keyboards (designated Model M6s, the keyboards that built the ThinkPad's keyboard reputation), then the M4-1 is the only one. The distinction between sleeve and dome in this case is that the rubber element isn't involved in pressing on the membrane inside, which seems to help mitigate mush (plus it's not in a dome shape). The aforementioned M6 is just an evolution on the M3 (IBM PS/2 L40SX laptop and keypad) and M4 design - they use the same rubber element, but differ in keycap slider design.
Otherwise, none of the other keyboards uses rubber domes from Lexmark. In fact, the only rubber dome keyboards from Lexmark I'm aware of are the Quiet Touch version of the Model M Enhanced Keyboard and the IBM Basic II Keyboard (aka, the "Model A").
The other rubber domes keyboards are a bit of a spectrum. The RT3200 was produced by NMB, the ones with 'K' at the beginning were produced by Chicony, and the ones with 'SK' are Silitek/LITE-ON. The RT3200 probably has my favourite domes but the keys can bind if you hit them on the edges. KPD8923 is a modified Chicony KB-5923, so if you tried one of those, you've tried this already. KPH0035 is a bit meh, to be honest. The rest are all scissor-switch rubber domes - IMO, SK-8855 and KU/KT-1255 are pretty close feeling to period ThinkPads at their time of release, but the 8835/884x family are quite different to their period ThinkPads.
