When you think about it, it's kind of strange we've been using the same type of computer mouse for the past 20 years. Other than trackballs and other navigation devices, the only significant change to the basic mouse has been the addition of the scroll wheel. But now there's a new twist to the old mouse. See this great innovation, tonight on "Tech Live."

Technology is supposed to make our lives easier, or at least more comfortable. Our PCs and workspaces have improved over time, what with better ergonomics. We at "Tech Live" are all about making your life easier and more comfortable. That's why we're pleased to show off the Evoluent VerticalMouse.

Nice to meet you

Using the VerticalMouse is like shaking hands with a very comfortable piece of plastic. Your thumb rests on a ledge, and your four fingers wrap around the right side. There are four buttons (three for your fingers and one for your thumb), which you can program for repetitive tasks. It also has a scroll wheel.

Feels good

Use the VerticalMouse for five minutes and you'll wonder why no one had thought to invent it earlier. Kudos to the good people at Evoluent for giving it a shot. It takes a little getting used to, but that's no big deal.

More importantly, your arm will feel better. That's because it's more natural holding your arm in the position of a handshake than laying it flat on a table. Stretch out your arm and then move your hand vertically and horizontally. Which feels better? That's why this mouse is so great.

Left out

There's one small problem: If you're left-handed, you'll need to either learn to mouse with your right hand or call the company and demand it manufacture a left-handed version. Evoluent only makes mouses that fit right-handers, but the company says it hopes to make a left-handed model in 2003.
