Installing programs on external drive. Benefits?

[(((k)))]

Are there any benefits to installing heavy programs to an external drive? Is there a way to move previously installed programs to an external?

The only benefit would be space but I think the cons would outweigh this greatly. My advice would be to just install them on the air, if you were out on the road (really what the Air is designed for) then if your programs were on an external drive you wouldn't be able to use them which seems pretty pointless!!

Well I installed Poser 5 on my 1 GIGhrz TiBook and, with all the add-on's, it took up GIGs of space and ran at the speed of sludge, so I dragged and dropped the whole caboodle to an external drive and run it much better from there because I have more hard drive space to use with it.
I suspect it depends on the program, some will work fine and others won't.

Try it and see?
