It’s always interesting to see the evolution of designs and products. A good friend of mine has had the chance to be a beta tester for Logitech’s trackmans since the start of that product. He kept a sample of every of the tested items and lended it to me so that I could take photos of it and share it with you guys. As you can see, the design was very basic at first and had an interesting evolution.
The very last versions of Logitech’s TrackMans are not featured here, but you can of course check them out on their website.
The very first one, for square-handed people
Rounding some edges
A bit more ergonomic, adapting to the hand’s shape
Adding a little scroller
Finally, the really ergonomic version.
