Thanks for all the feedback...i read the article about it and noticed it mentioned improvement for acpi power management and also lower ram usage in certain situations...so i was anxious to check it out...

When i tried a recent daily build with the 3.7 kernel i already noticed some improvements regarding power management, and it sounds like that will be refined even further with 3.8

Perhaps one of you 13.04 testers can make an announcement in this section when you get 3.8 in your updates...that way i will know to download a daily build and check it out
