Re: Use case?
I bought my own copy of Warp 3, probably not all that long after it was released given the dates involved here, for my home PC setup I was using to do postgrad work, because I was so incenced by how utterly useless Win3.1 multitasking was , especially when trying to run certain bits of software  which seemed to treat the concept of co-operative multitasking as something only other bits of software needed to bother themselves with, and how much of my time was being wasted as a result, that I was quite happy to spend my own money on something that would resolve it. Even in the cheaper redbox variant, I still recall it being a fair sum of money to be spending back then, but the reviews all said it could do what I was hoping it could, and I simply couldn't put up with Win3.1 any longer, so I picked up a copy the next time I was in town (oh, the good old days when you had actual physical stores selling physical boxed copies of software) and hoped for the best...
...and the first time I managed to get it up and running and able to fire up a Matlab session in one window, then seeing how responsive the system remained, made me realise I'd made the right decision.
 I first came into the PC world in '91 having spent the previous 4 years being seduced by the way multitasking worked on the Amiga, and simply couldn't fathom how hardware that had so much more raw power even then, let alone 4 years later when this anecdote was set, could possibly be this bad at running more than one thing  at the same time...
 Most notably Matlab, which once let loose on a calculation (given the work I was doing at the time, these could take an hour or two to complete) rendered the entire PC unuseable until it finished.
 I also used to harbour similar thoughts towards the Mac SEs I'd been using at school around 89-91, so looking back on it all now makes me realise just how far ahead of the game  the Amiga was then, and also how readily those of us fortunate enough to have used one simply took for granted its capabilities without necessarily realising that this really wasn't how home computers generally behaved.
 With the notable exception of the Archimedes. Even as an Amiga owner, that impressed the hell out of me, and still does.
