I own both TypeMatrix 2020 and 2030. Never really used the older generation, because I wasn't ready to make a switch and then the 2030 came along.
About the 2030, it's very solid, excellent portable keyboard, its scissor switches are the best I've ever used, built-in support for Colemak has been handy a few times, and at last but not least, the layout is a *HUGE* improvement over staggered QWERTY. Brackets and num-row keys are much easier to reach, so are B and Y, ZXCV doesn't feel awkward when touch typing with proper technique, the one-column separation works tremendously, although you need to move the whole hand to hit BS/Enter (but that's not that different from normal layout with these keys controlled by right pinkie). Two "bottom" rows are a great idea. Modifiers could use some remapping, but that's a minor issue. My only real complaint is that keycaps could be sweat-resistant. The skin isn't all that bad though.
