PSA time, I suppose: I've got a UK example of this keyboard, and it's no better than OK. The chiclet layout has ordinary-size keys, but the gaps between them (that the mechanism requires...) are larger than normal. The # key on the Sculpt is as far away from H as the Return key is normally; the Return key is another key further out. Very uncomfortable. Test drive before purchase. A big shame, because the key action is pretty good, the rearranged navigation keys are - as these things go - sensible, and of course the separate numeric pad is pretty useful. Independently-mappable space bar halves would have been nice though.
(If you have any friends in America, get one of them to buy you an American version. I bet they're much better, and the wider Return key will prove easier to reach.)
Quite why they just can't sell an MS Ergonomic 4000 with mechanical switches, I have absolutely no idea. Just about every other niche of mechanical keyboard fiend is very well served - except the people that want a split mechanical keyboard with a layout that hasn't been pissed about with. They're shit out of luck.
What I'd pay $$$ for is a Sculpt keyboard with mechanical keys. Nothing else, no new inventive designs, nothing crazy or very different, nothing terribly ugly. Just put some Cherry MXes onto a Sculpt and sell it to me. All the ergo-mech keyboards seem to either have significantly different layouts, or are just huge.
[Another thing I'd pay $$$ for: sell me a kit to move the keyboard/pad on an old ThinkPad X/T/W series to transplant it onto a new one. I used to use my X201 all over, all the time. With my T440p, I actually hate using it. As in, it's negative and I actively dislike touching the damn thing.]
