Screw Toshiba and Acer. Get ASUS. If you don't game on it or really rare, then get the Asus UL or U series. They are VERY LIGHT weight, AND has very good battery life for a good price. 5400 rpm drive with 1 gb graphics card with core i3 or i5 for some. Battery life on the website says 10 hours when it's actually around 8 hours.
