I imagine many do. First off, lately I've seen brand name, well-regarded 27" 4K monitors one can buy and have shipped from Amazon for $300 or less, likely with sales tax (U.S.). Unless someone is dealing with tight space constraints, getting a 24" monitor seems like needless sacrifice of potential space. I, too, date back to smaller sizes; I fondly remember my old Viewsonic 15" CRT monitor, a 17" CRT monitor, a flatscreen Dell 24" monitor for many years...now a 27" iMac.
Mac Pros are so obscenely expensive they might as well be sold on Mars as far as their relevance to the average consumer. Mac Studios start to look good when you decide to future-proof your Mac Mini by going to the Pro chip and 32-gig RAM, and realize the Studio for just a little more gives you more ports, a Max chip, etc...
