The first thing you'll notice about Microsoft's new $60 Sculpt Comfort Keyboard is the wavy design reminiscent of its earlier ergonomic models. But if you look even closer, besides a host of Windows 8 shortcut keys, you'll notice an enlarged space bar that's been split down the middle.

According to Microsoft's internal research, 90 percent of typists only use their right thumb to strike the space bar, leaving the left side mostly ignored. So they've thrown it a bone, turning it into an extra backspace key that's easier to hit without breaking your "typing stride." Unfortunately our own internal research found that 90 percent claim to be a little generous. So what do you think? Do you always use your right thumb, and only your right thumb, to strike the space bar? And would you actually use an extra backspace key down there if your left thumb wasn't used to it?
