That missing mouse feature..
I might have mentioned I roll a Logitech MX Revolution.There is so much that is great about this mouse, but I'm going to focus on one feature that; unlike many of its other qualities; could be reproduced in modern mice but sadly never is..
Automatic Free-Spin
Okay, admittedly other mice can free-spin their mouse wheel, but the MX revolution can do it in software. That's right; there's a servo or something in there; no button clicking required. When I start scrolling down some long document, my mouse behaves just like a regular mouse, but when I start spinning the wheel fast, it senses this and unlocks itself; starts free spinning, the document scrolling with it.
When I want to stop, I put my finger back down on the mouse, and in a moment I can feel the clutch re-engage; which is a highly satisfying feeling, by the way; and now my wheel behaves like any other wheel, except with better weight, balance and tactile feel than your mouse, guaranteed!
NO OTHER mouse can do this. Even Logitech's later wannabe-Revolution mice can't do this. Why is this? I don't want to find and click a button when I'm in the middle of a document; my spinning fast means get-the-fuck-on-with-it; I shouldn't need to begin a whole other operation to make this clear to a fucking mouse.
I must be thinking about my mouse. Yup, the left button has finally started double-clicking by itself. After what, 15 years of use? Pfff..
Given that it's already at four times+ its rated lifespan and I have (oh the wonder of forethought) three replacement microswitches in stock right now, it's not a big deal.
Gawd, I love this mouse!
And its duplicate which I keep for spares (still 100% intact).
