These dips (and on the other side, run-ups) are almost always knee-jerk reactions and overdone. They're nerve wracking but ultimately healthy for the stock. The weak holders panic and dump, giving those with some insight a cheap buying opportunity. The stock will come back, probably even make new highs, in a month or less. New products hitting the street are always a boost, and they're just too strong a company to flounder. Great product, strong vision of where they're going, and no sub-prime exposure.
