It appears that Thanko has upgraded their Silent Keyboard making it possible to use it with two PCs at once. A toggle switch over the arrow keys allows users to switch between computers, and its relatively low noise output (45dB compared to 60dB for a regular keyboard) make it an interesting choice for power users—especially ones that just blew their wad on a second PC. The Silent Keyboard 2.0 will only set you back $51. [GeekStuff4U via Crave]
