Do not expect all the same 11h of battery life (except perhaps with minimum brightness and turn off wifi? I have not tried), but it reached 8 without difficulties. Only negatives: the sound through the speaker is not great (like many netbooks, it improves with headphones), and there is pretty much useless softwares to uninstall the arrival of the product - but it's like that with all the pc.
Small mistake Amazon on this page: it is indeed the latest model from Samsung, released in January 2010! (And not in 2008, then.)
