Walmart has the Acer 13.3" Ultrabook Laptop for a low $449 with Free Shipping. It's $50 less than it was on Black Friday!

Design - Optimal Use

This very light 3lb laptop is perfect for transporting to work, school, or your local coffee shop. The 1,366-by-768 resolution is adequate for home and student use. The screen itself is bright and clear, displaying smooth text and graphics. If you need a bigger screen or do not plan to move your laptop around much, look for a larger notebook.

Key Attributes

It includes a reasonably fast processor designed for low battery use, and a smallish but serviceable 320GB hard drive along with a 20GB solid state drive that helps accelerate system performance and deliver faster startup times.

Battery Life
An 5.5 hour battery life is what this Ultrabook is rated for. Your mileage will probably be less of course.

Downsides to this model: No DVD/CD drive, last generation Intel Core processor, non DX11-compatible graphics.
