I loved th MS Sculpt (the "75%" one, with a layout similar to a laptop, only split). It started randomly failing for some reason, the only keyboard I've ever had to fail...
But I don't think that being low-profile was what was nice on the joints with that keyboard, but rather the presence of the palm rest which didn't force the wrists to bend upwards.
I now type on a "gaming" keyboard with full-size cherry switches, which is quite thick, and I don't have any wrist pain. Some 12 years ago, I used to have an Apple keyboard which was hell on my wrists, despite being quite low profile. The Apple didn't have a palm rest, the mech one does.
As to your typing speed remark, I suppose you already know that you don't have to bottom out your keys. I find I type faster on my mechanical keyboard than on laptops, and it's also easier on my fingers since there's no shock from bottoming out. It takes a while to get used to not press the keys all the way, but it's a much more pleasant experience. It's also quieter than the random HP domed keyboards we have at work or any laptop.
