I didn't want to bump the whole thread (as it's buried in the Developer's Corner) so
here is a link....this allows you to add an icon that appears on your computer (Win) when you attach your kindle via USB (instead of a generic usb drive letter). No hack or jailbreak required. I've used it on all of my kindles which makes finding and ejecting them easier, and it's kind of fun! Thanks to Mario1up who originally posted it.
