The sensor is adjustable between 3 resolutions, depending on task. At max DPI, my 1440p is navigable with less than a single swipe of the finger. At lowest DPI, pixel perfect stuff (such as photo editing, for example) is exceedingly easy. DPI is changed by holding middle click and then right click.
The trackball itself is fully laser optical while the scrollwheel is mechanoptical (scroll wheel turns a spoked wheel that a sensor interprets). The ball rests on 3 steel bearings, two set 90 degrees from one another and the third at 45 degrees. They're easily removed for cleaning and the trackball itself is held together by three phillips head screws.
Hope this answers some questions!
Edit: Also, you can replace the ball with a standard sized billiard ball, if you so wished. Edit Edit: Manufacture date of mine was 16 April, 2010, to give an idea how old mine is. Might clean it as a birthday present!
