Not quite a laptop but the iPad is close to being a laptop and at $499 it's the price point that Apple needed to be at to compete with the netbooks. Check out the video below. The book app looks pretty cool (flipping through pages with your fingers) and the virtual keyboard is similar to the size of a netbook's keyboard ... so for those of us who primarily use apps on the web (e.g. gmail, facebook, Akubo, etc.) this will be very interesting to try.
