Hey Mark, cheers :) I'm not used to asking for free trials, so I have no idea if that's going to work - especially seeing as how I live in Denmark! It's not exactly bursting with specialty electronics outlets here :) I also have my eyes on a Truly Ergonomic - https://www.trulyergonomic.com/store/index.php
. It's a bit more expensive, but it also looks very good, maybe a little better than the TypeMatrix, layoutwise. And it's mechanichal, which I read is the bomb, although I have no experience with it - it might be a bit noisy, which could detract from the value when I'm using it around other people.
I hope there'll be some sort of electronics mess in Copenhagen soon where I get the chance to try them both, but it's not likely.
