TOD: I'm often accused of being a Luddite because I refuse to get a cell phone and I don't TiVO (or watch TV), have a DVR, an iPad, an e-reader or too many gadgets outside of the computer that were designed to make my life complete.
I thankfully feel more complete without all of the above, so my answer - at least this early in the morning - would likely be my KitchenAid mixer and/or my food processor, both of which help immeasurably in the kitchen. The heat here in San Antonio is climbing above 90 most every day now, so you might want to throw in the ice cream maker, too.
I'm sure there's something else to go on the list, but I can't think of it right now.
