this is a switch that allows you to use one monitor,keyboard and mouse with multi towers. my question is does anyone here use one of these and if so is it electronic or manual. also how do you like it and what brand is it. im building a computer now but i plan on still using my old one but i don't want all the clutter of two monitors and junk. thanks for any help just want some advice on which one to get. i hear the manual ones freeze up the computers. have not heard that about the electronic ones. anyway thanks again.
