This 4-Port USB 3.0 Hub for iMac is an ideal must have for those who use multiple USB gadgets with their iMac. It's a simple design with four USB ports you can attach to the front of your iMac. So much so, it also gives you those extra ports without spoiling the beauty of your iMac. Additionally, the ports are aligned horizontally on this hub which just makes your life easier. No more twisting the cable to fit in those vertical USB ports anymore. And if that's still not enough, just think of the space you are going to save by attaching one of these to your iMac instead of going for a hub that sits on the desktop and eats up more space instead.
