That Thinkpad keyboard is awesome and a great idea! Does anyone know a site that shows you how to do it? Or is that flat ribbon cable to USB board in the picture custom?

While Lenovo still sells the wired version[1] (ThinkPad Wired USB Keyboard with TrackPoint), they regrettably stopped selling the bluetooth version a while back. Hopefully it's clearing stock for a refresh, but...
I think I need to buy one of these soon. My mechanical keyboard (an original Monoprice with Cherry MX Blue's) is starting to wear out, and I've been contemplating its replacement. I love my T420's keyboard (typing on it now) and "get" the pointer, so this seems very logical. Not sure if it's a "10hr a day" keyboard or not, tough.
I'm so tempted to build one of these. I love my X61/62 keyboard and would love one for work. I can totally print the bottom half for the keyboard with my 3D printer. The hardest part is finding the interface board.
