Re: Hipsters indeed
I not only constantly use the middle button but I have a mouse that actually has one instead of the "scroll" wheel: the Sun Crossbow USB mouse.
I love it so much that I bought as many as I could about 15 years ago and have been slowly going through my supply as they eventually wear out (it's usually the left button that dies first but the most recent one died because the little plastic rollers that contact the mouse ball simply wore out and no longer could reliably maintain mechanical contact).
I keep a wireless two and a half button (scroll wheel) mouse around for times when I really need that but it's honestly rare for the work I do.
Of course, I also have a Sun Type 6 keyboard with the Control key where [insert favorite deity] and Stallman intended, immediately to the left of the A key.1
I also bought a half dozen of those and have been slowly going through them as time and coffee spills take their toll.
Admittedly, this all probably says more about my lack of manual (and mental) dexterity as well as a certain perverse retro-pigheadedness than it does about the succeeding tecnologies but there you have it.
I suppose I'll eventually have to break out a soldering iron and cannibalized parts to keep the last mouse functioning, which, given the aforementioned lack of manual dexterilty, should be an interesting endeavor replete with verbal imprecations, singed fingers, and the smell of burning circuit board in great abundance.

1 I have honestly never quite understood the modern key placement of the Caps Lock key to the left of the A key, since the only use is in the ease of producing shouty emails.
