The last time I checked out digital cameras, they were little more than high-priced toys. A year later they're even more fun-but now they're worth the price.

I've just spent a few weeks with one of the new gadgets, Canon's $700 PowerShot A5, It's small enough to slip into your pocket but comes with enough memory to let you shoot all day. The A5 is easy to use and records sharp, lifelike photos with surprisingly good color fidelity and detail.
