Tiny Enough For Spies

Don't chuck that empty Altoids box--you may want to use it as a camera case. An array of supersmall digital cameras, including the stylish $400 Pentax Optio S, above, have hit stores, offering eye-popping designs, loads of features and sharp picture quality. Sony's candy bar-size DSC-U30 is the cutest ($200), Canon's PowerShot S400 the most rugged ($500) and Casio's slim Exilim the most likely to be confused for a platinum card ($280 to $400). --By Jeffrey Ressner
