It's inevitable: any time you make a big purchase, there's always something coming along a few months later that makes you (at least a little) regretful about opening up your wallet. So tell us: Is there anything you're holding off on buying? Whether it's a computer that you're waiting to be updated, a product with quality issues that need sorting out, a car that gets a redesign in the next year, or just a pair of shoes you really want but are waiting for the price to drop, tell us so we can all share in our longing together.
