Thanks for the kind words everyone. I'm exceptionally pleased with it.
For those skeptical of its practicality, I was initially worried about the same thing, but I've found that it's not too difficult to get used to, especially for writing. Since everything is so close to the home row, your hands aren't ever moving much even for complex chording. This makes lots of things that would be impractical otherwise quite practical on this small layout, like Fn-Cmd-Shift-[ to switch tabs.
Another thing I've noticed is that the layout is sufficiently different that my hands don't get confused when switching between it and a proper 60%. The switch is almost seamless, and I transition to the new shortcuts without thinking about it or making mistakes.
