    I am SO confused about this after watching keynote, reading forums, etc.

    The new MacBook Pros have a NEW type of battery, right? The 13" and 15" now have the same new cool, long-lasting battery as the 17".

    I heard somewhere that this new type of battery doesn't need calibration, that it auto-calibrates or something.

    True or false?

    Don't know, but I still calibrated mine. It certainly couldn't hurt.

    I have a 13" MBP Pro.

    When I got it I charged it fully, then started working unplugged. iStat had my battery health at 99%, then at 97% later in the day. After fully running down the battery and letting it rest, then fully recharging, I am at 100%. I imagine for the sake of keeping the meter accurate, the occasional calibration is still necessary.
