      Let it drain, charge it, let it die again.
      also should i make a bootable back up of the OS?

      If you can, yes.

        The last part of this thread made me curious about making bootable Lion backups. I like the thumb drive idea, especially for the MacBook Air, but for any unit. I use my MBP DVD drive so rarely that the thing was crapped out for a year before I got around to having it looked at...could have been in bad shape if I needed an emergency boot in that time. Anyway, I found this post to some "'donationware" that will simplify making the thumb drive: http://www.redmondpie.com/make-os-x-lion-bootable-dvd-flash-drive-sd-card-in-one-click-with-lion-diskmaker/. I have no personal connection or experience with this, just encouraging our new MBA owner to not put off this important task!

          I think the MB Pro is a seriously fantastic piece of kit. It looks great, performs superbly and the battery lasts an eternity. Nothing to complain about.

            FYI just read...http://support.apple.com/kb/ht1490


            Portables with built-in batteries
            Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure outlined in this article. These computers use batteries that should be replaced only by an Apple Authorized Service Provider.

            my new one has the internal battery that can's be changed except by apple so i guess calibration is not necessary..

              Initially my 2011 MB Pro had a 10 hour battery. This dropped to less than 6 hours after I installed Lion. When I had an issue with the keypad I call Apple support and whilst on the phone they gave me some calibration sequences and now my battery is back up on 9-10 hours.

                Care to share those calibration sequences? Anything more exotic than the usual reset the PMU, run down to nothing, then charge to full, and repeat?

                  It was more than 4 months ago. Call Apple support and just let them know that the battery life on your MB Pro has taken a nosedive and ask if they can remedy that.

                    Don't get me wrong, the MBA's are beautiful machines, but I feel that the MBP will always have the edge on it.

                        MBA got it's upgrade in July, which was more drastic than the MBP's. It'll probably go another 6-7 months before the next. The cycle is usually 10 months or so.

                        The MBP's update wasn't an complete overhaul, but just bumps in processors and storage. The belief is this incremental update will buy them a little time before they roll of the more Air-like, ultra-thin MBP's next year.

                        But you never know with Apple.

                          Ultra Thin MBP's, that sounds interesting.

                            Funny. I was just reading up on some of those rumours.. It sounds logical to me as well.. I still don't feel comfortable about being without an optical drive however, things are moving cloudwards on the whole and I know what Apple were like with the floppy drive, which turned out to be a good thing..

                              There is no reason for Apple (or anyone) to offer one in a laptop anymore. Not one. And I'm an old fogey and late adopter.

                              I haven't used my drives in my Mac Pro to do anything but rip my old CD's and rip DVD's for my son to use in a video player in years. And Apple makes money off of selling digital media to the majority of people who haven't ever ripped a single track of music. Heck, I have two opticals in my Mac Pro tower -- one is dead, the other is dying.

                              I expect the next big MBP update to go ultra-thin and for them to offer an optical drive version for maybe 6-12 months afterwards.

                                I don't think I'd miss the optical drive. My optical drive was on the fritz for a year before I finally got around to taking into the Apple Store for service as my AppleCare was about to expire. There were a few times during that year that I tried to use it, but worked around it sufficiently that there was no urgency to repair it. With backups over AirPort, software, movies and music all downloaded, about all that's left is a few music CDs I never got around to importing. That said, I DO have a mac mini in the house for CDs should the need arise.
