I dunno... The 5100 was heavy, did not include a case, offered no
protection for the screen, didn't run on batteries...

I think it's only portable in comparison to the mainframes of the time --
that is, you could move it from room to room because it didn't need air
conditioning or special power or anything. But that's true of most of the
computers of the time. Yes, it was a one-piece unit, but I don't think
that's really enough. You wouldn't have really taken it home to finish up
or to a client's office to do an audit.
