Apple MacBook Pro

Work (or play) for eight hours straight without stopping to recharge your computer’s battery. MacBook Pros carry a workday’s worth of power, compared with just five hours for similarly sized Windows machines with the same processor. Flat lithium-polymer batteries make use of all available space and are nonremovable to free up room usually used for battery connections and encasements. And they’ll last five years—that’s 1,000 recharges—thanks to a chip that sends juice only to the battery cells that need it, so the others don’t overcharge and burn out.
