Xton has a DZ60 and it's Vimtastic!

Mine has a split spacebar, no arrowkeys and an opaque case. Changes from the default layout:

Vim mode toggled by hitting left spacebar (see users/xtonhasvim). Reusing the capslock LED to indicate VIM is on.
Momentary directional control by holding down ;.
Mousekeys toggled with middle space button.
Escape is dual-function with control (which replaces capslock AS IT SHOULD BE).
Bottom left key is the "halp my kb doesn't work" key that always dumps you back to QWERTY.
