I have to confess that I'm a sucker for those bubbly TV ads that make whatever they're selling an absolute necessity-even though I know most of the time what they're hawking is absolute dreck. But while the quality of the product may be dubious, oftentimes the idea behind it isn't. Take Wallet Pix. I can't vouch for its quality, but it is a sound idea.



Many of us have billfolds with vinyl inserts for wallet-sized photos of family and firends. But what if we could replace those bulky inserts with a slim gadget that could display dozens of our precious pics in digital form? That's the promise of Wallet Pix-a credit card-sized gizmo with a color LCD that can hold about 50 snapshots. Wallet Pix seems like a brain gem to me, but I'm just a little hesitant about buying electronics from the makers of the Finishing Touch personal hair remover and the EdgeMaster self-edging paint roller.
