I swapped out the HHKB for my Filco Linear-R and boy what a difference! I notice most the change in layout more than the difference between MX Reds and Topre... I do really like MX Reds but they are definitely a different beast.
I love the Unix-y left Ctrl and backpace location on the HHKB. Wish I could do that with every keyboard without using a software remap utility.
The reason I swapped out the HHKB for now is that this is the second time I had a series of BSODs immediately after boot. It only happened with the HHKB plugged in once previously, and my computer has had zero BSOD problems ever. Could it be an issue with the keyboard over USB? I use USB to PS/2 adapters (fortunately my ASUS board still has a legacy PS/2 port) for every other keyboard and never had that issue, and when I previously swapped out the HHKB for a PS/2-adapted board, the BSODs went away. Still bizarre to attribute a BSOD problem to a keyboard, and to have it occur so sporadically (and seldom). There were USB issues on my mobo model so it could be that.
Anyway, I look forward to getting my HHKB back on-board and for my incoming Phantom which will provide the option of a more desirable layout.
