Lenovo unveiled the IdeaPad S10 netbook earlier this month. The Atom based IdeaPad S10 starts at $429. Laptop magazine got their hands on a IdeaPad S10 and published an early hands-on review of the 10 inch netbook.
Quote from the review: "The Lenovo S10 left a good taste in my mouth. I walked away from my 45 minutes alone with it only wanting more time with it. The solid manufacturing quality, along with its spacious keyboard indicate that, as a piece of hardware, the S10 is one of the best. However, it is too early to make a call on the S10 until we see some solid benchmarks and battery life scores."
