From the second paragraph of my own blog post I linked above:
> I use a Typematrix EZR2030 for over a year
So I did kinda checked it out. :-) It's Much better than your average keyboard, though I agree with hailang about not needing it to enjoy a sane layout. In my experience, a sane layout is the second best thing you can do to improve comfort. The first best thing was touch typing itself (most importantly being able to not look at the keyboard at all), and the third was the actual keyboard. I didn't try advanced keyboards such as the Kinesis Contoured though, so they may be more important than I feel.
