DPI in itself is just a sensitivity setting. I almost exclusively stay at 400 DPI.
The sensor haivng only 2400 DPI as the max means it can’t be one of the newer generation with flawless tracking. Until very recently the max tracking speed of sensors was low, so if you swiped it across your pad fast enough to would “spin out” and your aim/cursor would shoot straight up instantly.
Trust me, the mouse community on overclock.net and other forums is JUST as obsessive and scientific about them as we are about flashlights here. Logitech’s new wireless tech is such a big deal (and so expensive) because literally nobody has done what they have before and there is data to prove it. Now that the cat’s out of the bag I’m sure other companies will step it up and try to compete (rumors are something will be out SOONER rather than later).
Shape is always, always most important though (okay maybe MMOs and RTS games being the exception where you need lots of buttons?) and that’s why I wouldn’t use Logi’s wireless mice even for free.
My dad has a mouse not that old but fairly similar. The PC he had it connected to ran Windows… 3, I think? Crazy to remember how advanced that all seemed, I sure won’t miss dial-up though
