Great idea; as USB drives are becoming commonplace now, I think we
should have a hack devoted to them. Maybe you could divide the hack
into different sections for different configurations of flash drives;
you could have one for emergency computer problems/repair work, one
for applications, one for files, one for multimedia, etc. Since I
already carry my flash drive with me nearly everywhere I go, it just
makes sense to load on all the applications I use at my main desktop.
I get most of the applications I use from PortableApps.com, but I
sometimes am able to add applications not even designed for the flash
drive, such as the free version of Evernote, which my GTD process
revolves around.
