Has anyone tried W8 DP and tested it's battery life? if it's improved like they promise, it may be a better solution for my X220 than a clean Win7 which is worse than factoy with battery.

I have the X1, under Windows 7 I used to get around 5-5h30 of battery life, now with Windows 8, I can get slightly more than 6 hours, however my battery life will decrease much faster as soon as I go back to the Start view, because everything is in 3D so this can only be done in desktop view. The improvement isn't amazing and in my case, Lenovo's power manager doesn't work perfectly on windows 8 so I'm not sure that choosing Windows 8 over Windows 7 is worth it if Battery Life is what you're worried about.
