Hi guys, I am in college, and I am currently running a late 2008 MBP on my desk with a 22 inch Dell widescreen. I also use a wireless keyboard and mouse set up. With bose speakers. It basically a desktop set up with my laptop. And recently I brought up my PC tower up to my dorm, (basically to take some stress off my laptop, and play AOE 3) And I have the the Dell running on VGA in my monitor and my laptop in the DVI, I just switch them on the screen. Now I need help with what hardware to use my one mouse and one keyboard between both my laptop and PC tower. I kinda know what people use, but I need to know exactly how it works, what plugs into what, and where to buy this device. =] Thank you!
