While not a split, two-piece keyboard, I opted for the Kinesis Advantage 2 keyboard. It has the cupped wells that follow your finger lengths in 2 axes, and you don't have to fuss with two pieces, tenting, and adjustments. I can put it in my lap and it still works as well as at my desk. It is a bit big, but not as much as the photos I first viewed before buying it, and it is very light. The firmware is on the keyboard, so need to setup your computer to use it. Plug and play with multiple computers. The Moon Lander looks spectacular, and their marketing is more polished, but the Kinesis is my favorite.
