We work in front of our computers way too much to not be comfortable. If your mouse is starting to mold, consider upgrading to one of these:
The 5 Most Comfortable Mice
The Logitech Wireless Trackball M570 offers a wide, comfortable grip, but the real appeal here is the trackball. What could be more comfortable than not having to move your arm at all? This hot-selling model offers exactly that.
The Gyration Air GO Plus mouse allows you to ditch not on the cord, but the table all together. It will work as a comfortable table-top mouse, but you can also pick it up. You hold it like a gun and hold down the trigger underneath. A great solution for conference rooms, but fair warning: the sensitivity on this air mouse is very high. Those with shaky hands may cause board room seizures.
For the constant computer user with sensitive wrists, we have The Evoluent Vertical Mouse. Flipping the traditional mouse 90 degrees on its side, the Evoluent allows your wrist to extend into your hand without the twist caused by traditional mice, which can lead to acute pain over time.
In the “If it ain’t broke don’t fix it” corner, we have the beautifully designed Logitech MX Revolution. No new age tricks here, just a wonderfully optimized wireless mouse with a smooth finish and comfortable grip. People who buy this mouse adore it, in great part because of its extremely precise and fluid scroll wheel. The lifespan on the rechargeable battery tends to impress, as well. Its pricey, but if you work in front of a computer all day, you could find it money well-spent.
Many people love the Kinsington SlimBlade Trackball because of its extremely low profile design. Even more comfortable, however, are the four programmable buttons it comes with. Using the software they provide, you can program these buttons to the functions or keyboard shortcuts you use the most often.
