I know, I had this kicking around on my drive for months without posting it, so here it is. It's Notepad++ made portable. It automatically backs up and restores an existing Notepad++ registry key if there is one (and cleans up after Notepad++). It also has session support built in, so you can have the same set of files open from your portable device on each PC you move to (it adjusts the paths for you automatically). It does the same for the explorer plugin if you use it (remembering the path on your portable device that you had open), so it's handy for folks editing whole sets of code files or websites.
It's about a 1MB download, about 2MB installed and it's in PortableApps.com Format with a PortableApps.com Installer so it'll automatically install into an existing instance of the Suite.
