somebody is having trouble getting work done on a system that (a) is single-tasking, (b) has no hard disk, or (c) has an address space smaller than 16 megabytes. This is as of mid-1993; note that the threshold for `real computer' rises with time, and it may well be (for example) that machines with character-only displays will be generally considered `unreal' in a few years (GLS points out that they already are in some circles). See bitty box and toy.
