Sun “Type 7” USB keyboard and optical mouse now available
Sun now has the Type 7 USB keyboard (in UNIX or PC layouts) and optical USB mouse available. The keyboard features a built-in USB hub.
I could not find a price listed for the Optical Scroll Mouse, but the PC-style keyboard (X3731A) and UNIX-style keyboard (X3738A) are $50 each at the online Sun Store.
