Who can forget Microsoft's big splash into the gaming world with the Xbox? Unfortunately, the gaming gizmo wasn't much of a looker, but that didn't stand in the way of the console's success. The first Xbox and its bulky controller look completely bloated in comparison to its successors, which sport much slimmer, sleeker designs. In fact, the original Xbox controller was so bulky that Microsoft eventually switched to a smaller design (Controller S, seen above) that proved much more popular. Thank goodness Microsoft eventually toned down that tacky "X" branding!
