I *routinely* do things in parallel in different windows.  At its most
extreme, this means using several windows on my Sun to watch debugging
output from rlogin sessions running communicating network peers on
other hosts.  Without these windows, I'd have to debug my distributed
application off-line, losing the time-relationship between events.

I also frequently fixing source-code errors while the compiler in
another window is spitting out its error messages.

These are extreme examples, but I'm virtually always doing things that
I consider multi-tasking, meaning things that I could not do without a
multi-tasking system - and a simultaneous-display window system.
