I've not had as much time with the TB as I would like yet. Some egg/chicken problems, I want to have greater accuracy to edit in vi and I'm not going to get it without practice. Touch typing on whatever keyboard I'm using is going to help.
If you've strayed, I suggest that you all force yourselves back to touch typing. My big, rectangular keyboards have motivated me to evolve my typing away from ten-fingered-touch-typing over the years. The TB takes up minimal space and if you are looking around on the keyboard for that symbol that you want, it's likely that your fingers are covering up the keycap that you are interested in. Removing your hands, taking your eyes off the screen, tracking down the symbol, and replacing your hands is going to be tiresome.
I did some screen captures from the iPad app and stitched them together with the GIMP
I find it's much better to keep my hands in place rather that lift, search, and recalibrate.
I want to adjust the printed map to be higher contrast, the green on dark gray is not conducive to quickly recognizing the symbol. I think that's a bit of a problem on the physical keyboard as well, the green printing should be higher contrast. Maybe the inks could even be florescent so that if you had a small UV LED nearby, you could have a temporarily high-contrast keyboard without violating WT's desired aesthetics.
