The S7 is an aluminum ultrabook running Windows 8. They claim that it is the smallest ultrabook being 12mm thick trailing behind the MacBook Air at 11.8mm. But remember the MacBooks isn’t running Windows 8 and does not have a touch screen. the S7 will have full HD displays at 13.3 inches and a 11.6 inches model with prices of $1,799 and $999 respectively. The 11.6 inch model is reported at 9 hours of battery life with the 13.3 inch being at 12 hours. They have not announced many details such as the CPU or GPU but I will keep you updated as the conference progresses.
