Acer Aspire One D150 KAV10 Netbook 12Hour Battery 10.1" WinXP 160GB ATOM 1GB RAM
I'm not sure if any Browsers support WinXP anymore and have been unable to get a Browser working despite being connected to Wi-Fi. Standard Battery lasted just over 2 hours (2Hr 40Min) and Extended Battery lasted a whopping 10Hours.
