Preonic keyboard puts the keys on a grid

For a while I switched to a tiny ortholinear keyboard, the Planck, but gave up wrestling with both a new layout and the lack of unshifted numbers. But the Preonic, being offered in a month-long group buy at Massdrop, is tempting me with all its extra keys. It's $130 and requires assembly (soldering the switches, but not the board), with some case and keycap options to pick from.

(If you're wondering, these are for people who hate typing fast.)
