Beyond that, though, I don't know why the backup frequency should correlate with intensity of computer use. Time Machine only backs up changed files, so if Rita's not using her Mac much, Time Machine will wait patiently until she does.You're correct, of course, but much of the beauty of portables is that they
are portable, and having to keep an external HD attached when you're both moving around
and not doing anything that necessitates frequent backups defeats...certainly greatly hampers the portability.
