I love a big loaf of crusty bread, and slicing off hunks the thickness I want. But for every day sandwich (or French Toast) making? Yeah, I want it pre-sliced. Here's the history of the bread slicing machine.

Archie Goodwin (the fictional one created by Rex Stout) called it "that god-awful cellophane special." I guess Fritz Brenner's bread would spoil anyone.
