I currently run two computers for my use in my office, a desktop ad a
laptop, these are my primary machines... and I'm about to add two
more.. A Linspire box and a mac mini...

The linspire and mac-mini will be seldom used, just for testing my web
developments on those platforms, and I'd rather not clutter my office
with keyboars mice and monitors..

I don't know if such a thing as this exists, but I am looking for
something I can plug all the components of my windows desktop into and
from there, plug this device into all three machines, or at least two
of them, and then just switch back and forth between towers by
flipping a switch on this device, That way I cook hide my mac and
linspire box out of the way but still have full use of them from my
windows system's keyboard...
