Because the PCs at college had 133 MHz CPUs and 32 MB of RAM - multiple 
times the Amiga's 7 MHz CPU (admittedly of completely different design) 
and 2 MB of RAM. And yet, on such a machine, even something as simple as 
closing a window causes huge amounts of disk thrashing.

It didn't seem to me that that was the problem. Lacking graphics 
hardware acceleration doesn't make the HD thrash. And anyway, I thought 
the original VGA board had 2D acceleration?

PCs today have finally reached the point where they're about as fast as 
an Amiga for basic windowing operations. But it's taken an awfully long 
time.

Or you know something I don't. (Such as... how to operate Linux.)

That pretty much describes me and Linux. Even something trivial like 
configuring a network interface without DHCP seems excruciatingly hard 
in Linux. (As best as I can tell, you have to hand-edit half a dozen 
files, invoke cryptic commands, and so forth. It's a nightmare.) Under 
Windows, you just right-click on the network interface and type in what 
you want the settings to be.

Presumably that depends on what you're trying to develop, and with that. 
Certainly Windows is not designed with developers in mind.

...why in the name of god would you ever want to do such a thing? And 
wouldn't that require reading every individual byte of data on the 
entire HD anyway, regardless of OS?

I'm not a fan of scripting languages. They tend to be too ugly and 
messy. Besides, I've never found anything I wanted to script [which is 
actually scriptable]...
