DPI settings for trackballs?

As I am looking for a trackball, I see that some of them claim to offer "DPI Settings". Typical settings are 400, 800, 1200, 1600. The product descriptions claim that these settings control how far the cursor moves with each movement of the ball. At one end, the cursor will move very slowly allowing for very accurate positioning. At the other end, it will move very fast making it easy to get to anywhere o the screen quickly.

This article explains that the DPI setting can also be controlled at the Microsoft Mouse and Keyboard Center in Settings.

So, why do we need DPI settings in the trackball itself? Is that just so I can change them on the fly without having to go thru Settings or are the trackball settings more accurate?

I am just wondering if I should even care whether the trackball has its own settings.

Thanks

This is anecdotal - my experience only - but I have been using mice for 30 years now and I have never concerned myself with their DPI. I have only ever used whatever the default setting is and have always been satisfied with the results, and that includes designing circuit diagrams and component layouts using CAD applications. I did try a trackball once but decided to go back to a mouse.

I feel that you are over-thinking this. find one that your hand is comfortable with and go with it.

The DPI (or mouse sensitivity) settings in the device are there to cope with operating systems which don't allow you to change it there - so an added, though usually unnescessary, feature.

I wholeheartedly agree with Chris and MoxieMomma on this - if you can, go to a store and find a (preferrably wired) trackball that "feels" right in your hand - the detailed specification of the device probably don't matter at all.

What? Overthinking? Me?
