I'll start by admitting that I realize the Apple Mighty Mouse is beyond deprecated. I'm a musician and programmer, and I work on both Mac and PC. I continue to buy a "new to me" discontinued, re-conditioned, re-certified, pre-owned Apple Mighty Mouse every year or two for this reason: the scroll wheel performs in two axes.
In case you haven't had the delight of a massive spreadsheet (Excel), or a musical score (Cubase), the Mighty Mouse is the only mouse I've found that lets you scroll both horizontally AND vertically without a key combo. It's magic. (I know, I could get a Magic mouse - but I refuse to use a wireless mouse - they chew up batteries and the tracking on any wireless mouse has always been terrible compared to a wired mouse, in my experience).
Sadly, the design of the tiny scroller ball is such that it gets gummed up with "hand cheese" after a year or so and is so small that repair is impossible without breaking.
It's USB2 and I have a KVM switch. The Mighty Mouse (wired) continues to be the only mouse I can find with only the buttons I need, none of the buttons I don't need and don't want and an X-Y scroll "ball", and it performs flawlessly on both Mac and PC through a KVM switch. The one flaw is the inferior size, shape and durability of the scroll ball sensors. Such a shame.
If there are alternatives out there, I sure haven't found any.
Do you know of any other mouse that has an X-Y scrollwheel capability?
I have programmer friends that can chat at length about how awesome their 100db mechanical keyboards are. Yet none of them can tell me about an equally amazing mouse. It's oddly absent from the internet.
I'd be very interested in your recommendation for a decent replacement mouse, USB2, wired, and why. I am not interested in any gaming mice! No extra buttons. I've found nothing for a professional graphic artist or musician who is looking for quality and durability.
