sorry think i've got it wrong. I thought portableapps could be
run from a memstick on Linux - so i'm wrong apologies for that. It is a
full version with mods to stop writing to the registry. I do have a
limited requirement for running apps from a memstick but i find it most
convenient for using two machines (home and work), and having all my
settings for FireFox and OO for whatever machine i'm using. When it
comes to updating life is so easy, one just copies settings, deletes old
version and install new. I am only starting to get into Linux but still
use windoze for most things at present.

Just for a taster he's a list of a poster's portableapps. Maybe they can
be run through wine.
