How many of you use portable programs and what ones do you use?
I find having a portable version of GIMP handy, as well as portable Winamp lite and FLV player. I've also started using Cornice as an alternative to Windows image viewer (partly for quickly accessing my common image folders, but mostly because I can set it to flip through my images randomly). Interesting thing about Apophysis is it requires no installation and can be run from a flash drive easily. ClamWin, Notepad++ and Miranda are also installed on my flash drive but are somewhat rarely used.
