My first board was a Choc Mini w/ browns. I sold it within days and bought a Filco, here's why:
Layout:
Don't like that the F-keys aren't clustered, I'm used to it and don't want to change.
Shrunken Win-key. I like the modifiers all the same size.
I would prefer Home and End to be physical. The 3 different LED keys could have been Fn-d.
When I got mine the key-print was really very dim. If they haven't fixed it (I hear they have, but haven't seen it) then that would be a complaint as well. Built quality was great and I loved the feel and sound of the keys. This led me to get PBT caps for my Filco.
