    how much is the battery life with the i7 upgrade, compared to the 13-inch i5 1.7GHz?

    I got this model the other day, it runs really well (if not a little hot for my liking), and I can usually expect roughly 6 hours on average. However, if I'm sitting there playing games maybe only 3 hours or if I'm just browsing online only maybe 7 hours. (All times with wireless on and medium brightness)

    I was getting about 5.5 - 6 hours out of my i7 13 with WiFi enabled, Bluetooth off, keyboard lighting off, and screen brightness about 4 notches from the lowest. This was just casual surfing and a few apps like MS Office 2011 running.

    I'm returning the i7 and picking up the i5 though because the cost savings via the Amazon deal is too good to pass up.
