It is possible to order the kit without switches, and the caps are additional, thus, if you do not have use for them just do not buy them. You will have to option to source them anywhere else, even at your own stock.
I'm probably gonna have to buy them, as I'm not sure about the right shift, and it might also be a good idea to leave the 4 blank right modifiers as blank, and mainly because I have a thirst for PBT's
Not sure how SP ABS's compare to PBT's tho, hope the texture differences etc. won't throw me off too much, I guess I will soon see how they compare, really excited
Decided to get the TEX Alu case too, as the default case is cool, but not feasible because of the non-rubber contact points, I don't want to destroy my desk just yet
TBH I'm not a fan of the HHKB layout (the 1x keys above \ are a huge no-no for me), but I got an infinity both for the novelty of the bent metal plate and I wanted a completely programmable 60% cherry clear board. The programming method that HaaTa has come up with (the KLL) is actually really powerful.
I think I might have to put another one together tho, the lack of a proper backspace key is killin me.
backspace bothered me a lot too, but I got excited by the backspace + delete combination possibility, also if you put arrow keys there, they might also make good macro keys, like Home+End etc. I'm not sure about the order of the delete and the backspace tho, backspace + delete makes sense, yet probably delete+backspace is better reflex-wise, as the finger tends to click the edge of the keyboard for the backspace, so to sum up, yes the backspace issues is ...
EDIT: most probably mapping them both to backspace and adding a cmd+backspace=delete mapping would be saner, as delete isn't used that much
