Well, not always. For example, someone might come up with a GUI widget
library like GTK or qT in order to facilitate cross-platform applications.
This would be a third party library not bundled with the OS, but which might
be used by several applications. I had assumed OSX did "something smart"
with respect to these shared libraries, rather than having multiple copies
of them around.
E.g. I thought maybe the icons that represent the application were
actually an archive of some sort which contained the application *AND* the
libraries, and the OS could detect duplicate libraries and have them share
the same location on disk or something like that.

I like that you can delete programs easily in Apple (as opposed to
Windows, where you have to do an "uninstall" process which Microsoft is
trying to standardize, but which some third party apps do in arbitrary
ways). I'm neutral about the unmounting a USB pen thing. The first thing I'd
try is right clicking on it (assuming I'm using an Apple with a right mouse
button), and Peter's reply seems to confirm that works.

That may have been true in earlier versions of Windows (3.1?), but I
just tried resizing from the top left in XP, and it seems to work.
