Pros: Really great alternative to a mouse. Drivers work every time on Windows start up. Scrolling feature is faster and smoother than scroll wheels I've used. Basically, unless you're on a Linux system there are no cons IMHO. Even dropped it a few times and the ball stayed in place.

Cons: Hit and miss with Linux installations. Works great at first but not so great after restarting the system. You can find the Linux drivers by entering these commands in a Linux command prompt.. sudo apt-get install gpointing-device-settings sudo apt-get install libgpds0 Some programs on Windows and Linux systems do not support scrolling.

Overall Review: Firefox supports Trackman Marble scrolling.

Pros: Great for games and design. I couldn't imagine playing or designing anything without SSD. The read/write speeds are incredible on both Windows and Linux. This does work with Linux.

Cons: Should have got the 128GB but no real complaints.

Overall Review: This gets hot just like a mechanical drive does. Especially if you're getting one to update a laptop. Check for over building heat after installation before leaving it alone. I can not stress this enough if you're using a laptop. Other than that, great buy.
