Overly complex, hostile dialog is painful when your computer comes with one of those 6-in-1 card readers (as does mine), an external hard drive, and a USB thumb drive. Unchecking “display device components” leaves unhelpful, undistinguishable entries. Takes up to 3 clicks to eject a device, so most people just pull out their USB drive when das blinkenlights are off.
I'm aware that left-clicking displays a simpler menu, but many people (including me up until a few days ago) aren't aware of that feature, since third-party system tray icons don't always respond to a left click.
I know I can also go into My Computer, right-click the drive, and hit Eject, but for some reason I always forget that that option is there. Mostly because I don’t think of ejecting a thumb drive or external drive like ejecting a floppy or a CD … the latter involves something physically ejecting/launching out of the computer; for USB devices, a more accurate word or analogy should be used.
Add the drive letters, add the device names, and get rid of all the worthless tree-level stuff; it’s a programmer’s view, not a user’s view.
In 2008, we no longer need to be calling these things a "USB Mass Storage Device."
