They were great until you accidentally pushed one or two of them into the trash, and then your contact info was REALLY GWTW all right. A friend realized with horror she'd done this but the small business she worked for miraculously didn't seem to miss them.
Talk about "never going back again," I don't miss the clutter and I LOVE having everything in 1/8 of a cubic foot of space -- my laptop! (Wait a while, why is there still all this clutter?.....)
