I used to be the ultimate gadget freak -- if it did something special, I would buy it...til I realized my kitchen was overflowing with expensive unitaskers and I gleaned the vast majority of it (and haven't missed any of it, by the way. I shudder to think how much money went to the Goodwill in that box that day.)
Now I've swung the other way -- I cling firmly to "if it ain't broke, don't fix it" -- and I tend to shun the newest, greatest tool because I don't want to spend money I could be spending on good traditional stuff, then throwing away the "new and improved".
My current love is silicon bakeware -- I was given a set of silicon muffin cups and hemmed and hawed until the kiddo needed cupcakes for school and I was out of papers.
Whoooaaaah. They rolled right out of the cases, no sticking, perfectly baked, and I tossed 'em in the top rack of the dishwasher. No scraping baked-on crud out of metal pans, no rusting, no weight, no hogging my cabinets (no clattering scaring the dog to his hidey place under the table)...and three dozen muffin cups stack the size of a Coke can in my cabinet and weigh next to nothing. I am in luv.
Needed a new loaf pan (the last one rusted through) -- same thing -- a loaf of banana bread just lifted right out of the new silicon pan -- the pan washed clean with no scrubbing, and weighs nothing (and I can jam it in a strange corner)
Anybody else have something they've been a real Luddite about, and now you're wondering why you waited so long?
