It goes without saying that you have to be a pretty accomplished typist to use one of PFU's letterless Happy Hacking Keyboards. But for the laser-focused overachievers out there, PFU just started selling the S-Type for "speed" and "silence." This retooled version promises to keep up with faster typists -- a mighty vague claim indeed -- and pledges to make 30 percent less noise. Of course, as with other HHKBs, mere mortals prone to spelling errors can nab one with letters printed on the keys. It's on sale now for ¥30,000 ($371.61) -- a veritable steal compared to some other keyboards we've seen.
