I've been using traditional optical mouse devices. But due to small desk space, I wanted to try trackball devices. The idea was that trackball device stays in one place so I wouldn't need much desk space. I got the Logitech Cordless Trackman and man am I ready to go back to good old mouse devices!!

Cons:
- After a day's use I am feeling pain in my thumb, and fore arm. Classic Carpal Tunnel symptoms!
- While the trackball is quick in movements, it is difficult to work with when you need to be very precise. So clicking on small buttons requires multiple attempts.
- Click 'n drag / Drag 'n drop actions are quite tricky. Not as intuitive as with traditional mouse devices.
- The device comes with a sensor that is huge. Almost the size of a mouse itself. As I said, I wanted to reduce the space required on my desk, and I ended up having gained very little!

Pros:
- It's a large device. Good for people with large hands. Provides a lot of support.
- Easy connectivity. I'm using Windows XP. Plug 'n play!
