WSJ.com: Sharp's Zaurus Fails to Deliver On Its Performance Promises No Linux PDA for Walt: "Sometimes a new technology product looks great when its maker demonstrates it, but behaves poorly when you actually use it. And sometimes a new technology product is touted for some underlying techie feature, but in actual use that feature turns out to be either irrelevant or an actual disadvantage to mainstream users... Sharp's new $499 Zaurus SL-5500 hand-held computer, which I've been testing, unfortunately fails both these tests."
