Good people - I'm looking to buy my wife a new 13" notebook. Preferably the MBA. The MBA would mostly be using this for on-the-go office type software and internet, but with occasional gaming at home. Almost always Diablo 3 and Bioshock 2 (she's not a gamer and sticks to what she likes). A similar discussion on the MBP forums indicated that the HD 4000 in the 13" MBP could ~reasonably drive Diablo 3 at Low graphics levels. Would y'all expect the 13" MBA to be able to drive Diablo 3 at reasonable frame rates, even though the MBA has a slower CPU and comes (stock) with 4GB memory? thanks!
