Pro Swap-able, dual-battery infrastructure
Over 8 hours of continuous web browsing out of the box, which can be doubled to 16 hours by swapping in the extended, 6-cell battery (hot swap, so the swap can be done while the laptop is on, thereby not interrupting laptop operations).
Con Extended dual battery adds weight
6-cell extended battery adds 0.4 pounds to take this ultrabook's weight far above that of the ultrabook standard (<3 pounds).
