Bingo....well, quasi-bingo.  

I agree that there isn't much yet to use up 7 meg.  VM would presumably be
more useful to people with only a couple meg.

There are huge memory applications forthcoming, however.  A 4000X4000 24-bit 
plane image (good enough to record with sub-film grain resolution onto 70 mm
film, I believe) takes up 48 megabytes.  Of course you'll want to keep it 
entirely in RAM -- accessing it via VM into a few meg would take an 
excruciatingly long time.  You'll want an undo buffer, too.
