I've got a Mac Pro, a PC, and a Dell 24" LCD. Since the Dell has both DVI and VGA inputs, I plan on putting the Mac on DVI and the PC on VGA. Therefore, I only really need a USB mouse/keyboard switch. I've searched other threads and people were more concerned with the video part (understandably so). But all I care about is switching my Logitech G15 keyboard and G7 wireless mouse as reliably and quickly as possible. Any suggestions?
