All the parts arrived, and today was the big day: I built another Kinesis Advantage keyboard with Cherry Blue key switches. (Planning phase here.)
Technically, this is the new Kinesis Advantage2 keyboard: the most notable differences from its predecessor (the "Advantage") are that the nasty little function keys now have real mechanical key switches behind them so they feel somewhat better, and the home row keys have gone from medium blue to baby blue (not so keen on that change). The physical layout is identical: I assume the internal electronics have been somewhat updated.
Here's the page on the build process (lots of photos and notes).
