I hate bloatware, but I needed Adobe to sign PDFs and edit Illustrator files.
UPDATE: I now sign PDFs with pdfescape.com if I don't care about the digital signature, and I edit (simple) Illustrator files with Inkscape.
Installing Adobe CS5.5 brings on a bunch of crap I most likely don't need, and part of that is a service called Adobe Switchboard, for which (of course) Adobe has no clear documentation.
The only information I found was on eHow, but I generally distrust DemandMedia properties.
