The one with US-Layout[1] that went for 200¤ doesn't appear to have been
relisted yet...
I actually spent some thoughts on bidding on the one that ran out with
no bids, but declined after a little experiment: I simulated a split
board using two G84-4100's next to each other.
At first, typing with the hands that far apart was horribly confusing.
The error rate remained annoyingly high for quite some time. After half
an hour the dizziness waned, and I actually reached my humble 80 wpm.
When switching back to my MX11800 I was shocked that I could no longer
type on it without a scary high error rate. I again needed half an hour
for it to get down to normal.
I decided not to mess with my motor neurons like this again until I
develop RSI and have no other options.
