I like the Mac a whole lot better than my PC, but there are still a few areas of wonkiness. This morning, I killed the Finder by double clicking on the 2 GB USB icon on the desktop.
Now, that seemed odd to me - the first thing I thought was "oh crap, what now?" However, I recalled that I had ejected a "phantom" CD yesterday, and then it clicked. After rebooting the machine (thank you, ssh access!), I plugged the USB stick back in. Sure enough, it came up as both a drive icon and a CD icon. The trouble comes if I eject the "phantom" CD. That turns off the USB stick, but it still looks like it's on.
Some kinds of wonkiness are not limited to Windows...
