I know they're not cherry/topre switches, but I just wanted to note that this keyboard on my Thinkpad X220 is IMO more similar to the 75% keyboards than anything else, in part because of the arrow key placement and its width. Also, the Apple Wireless Keyboard is essentially a 75% keyboard, though I know it lacks a few keys. In fact, the keyboards on all mac laptops are essentially 75%.
So while 75% may be niche in cherry/topre keyboards, which are themselves quite niche, it is actually well represented in laptop keyboards.
I slightly prefer my Keycool 84 over my Noppoo Choc Mini.
I suck at Starcraft 2 and use F2 to select all my army. On a HHKB, that would require two hands with the Fn placement. Perhaps someone will say I should be using control groups for my army on 1 and 2. But then again if I were good I would want to use F3-F6 to move the camera to my bases, so the problem still stands.
Of course I use F keys for a ton of other things too, like driving a debugger and switching virtual desktops and moving windows to different virtual desktops and midnight commander and tons of things in Emacs and Excel and it's just nice not having to use an extra modifier key.
One nice thing about using a 75% keyboard is that when you inevitably have to use a laptop keyboard, it's not as much of an adjustment.
