At the moment I really only use my laptop, and I use it everywhere, so I am stuck on a trackpad. I recently purchased a Mac Mini (An impulsive buy after my first paycheck, but I like the Mac world and have been out of it for 7 years, so I figure there is worse I could have done
) and will need to get a keyboard and mouse once I get down to college, so I am now on the lookout for wireless keyboard/mouse combo's. I wish Bluetooth keyboards/mice weren't so darned expensive.
I used to have a Logitech MX1000 laser mouse, which was fantastic. Couldn't tell the difference between the response time of that and an optical mouse, but it was wireless, no need to buy AA's, and the battery held a charge for a long while. Fantastic little creation right there.
Used to have a trackball until I tried games. Something seemed off about the combination. My dad won't use anything but a trackball.
