    Apple should simply have claimed to have invented a better battery.  This would be easier for the morons that call themselves tech journalists and financial analysts to comprehend.  Giving the details how Apple achieves superior battery life appeals to us geeks, but it confuses the idiots whose pea brains shut down before they get to the result of longer battery life.


     


    Just tell them you've invented a lithium-titanium battery with 50% longer life and they'll go ape-s***!



    Couldn't agree more.  What people really care about is speed, weight/size, battery life, and screen resolution.  Adjustments to any of the four require tradeoffs to the others.  Apple decided to use almost all the hardware improvements this year to increase battery life.  They are going to get an apparent speed boost and additional battery life from software.  IMO, this was totally the right move.  The competition is abismal when it comes to battery life.  Apple could have just sat back and said, we're the best, no need to improve.  Instead they kicked the competition in the nuts; and they kicked them hard.  The competition is now 5 years behind in the balance between battery life/ speed/weight/resolution (and the gap continues to grow).

    My guess is apple focused on battery life because they don't have a suitable retina display for the macbook air (without killing battery life and margins) and they don't wan't to change the size of the MBA b/c of the cost associated with tooling the machines that produce the aluminum unibody.  If you don't want to upgrade the display or change the size, the obvious solution is improve battery life.

    I'm wondering what features will get skipped for the Core 2 Duo models... Anyone know?

    It's a thing of beauty. Some minor bugs (it's still early, obviously), but it seems to perform better than ML (and ML did beautifully on my hardware.)


    I have this exact model, also with the 6GB RAM upgrade.  Can you tell me if the Maps app works?


    How about the multiple displays with their own dock?


     


    Just curious- it's how to get any feedback for this old model. She is still plenty fast!  I've added a Corsair GT SSD, a Seagate 500GB hybrid drive in the opti-bay, and USB and eSata via the expresscard.  


    How about you?

    There's no question Mavericks is making OSX the most advanced operating system in the world even better. Quite the contrast as Windows 8 goes into the tank while OSX Mavericks is being praised.

    You are most correct here, I've been going through the WWDC videos and can confirm your description, Mavericks will be the most advanced OS in the world when it ships. Many features will go directly to making for a better user experience. I'm also left with the impression that Mavericks will in effect upgrade old hardware by performing better and focusing resources on the app the user is involved with at the time. Simply put Mavericks could allow many to put off hardware upgrades.

    There is much that hasn't been released publicly but to summarize not much hasn't been touched.

    Anybody know if current apps need to be updated to take advantage of App Nap? Lightroom and Photoshop are brutal on my battery life.

    Please read the article again. If that doesn't clear things up get a developers account and view the related videos. In a nut shell though App Nap is about background apps. If Photoshop or Lightroom are in the foreground you will not save a lot of battery life. That of course assumes that it is the foreground components of these apps eating up your batteries.

    If it was obvious everybody else would have done the same thing. Beyond that good improvements come in increments. You need better battery life before you focus on new screens that demand more power. Each increment builds on the previous.

    It is sort of like when Apple introduced GCD and lib dispatch. You have to install the foundation before the app writers can take advantage of it. Even then it may take more than one rev to leverage the feature. This is why OpenGL 4 support is so important, it takes awhile for developers to take advantage of such suPport.

    Maps app appears to work just fine.

    Multiple displays . . . I only have a main display (24 inch) in addition to the MBP's display. Works as promised.

    I have to say, the early '08 MBP is solid as a rock. A great machine. And as you said, still quite fast. She performed beautifully with ML, and seems to run even better under Mavericks.

    This is cute.

    If you download an app from the Mac App Store, but you haven't used it yet, it will show twinkling stars around it in Launchpad (to signify that it's new and you have yet to run it.)

    Damn you apple for making me want to buy all your stuff...



    This is the exact reason I just upgraded my MacBook Air. I have had an 11" MacBook Air and it is my favorite Mac I've ever owned, besides the battery life. I was going to get a rMBP but with the new enhanced batteries on the 11", I went ahead and ordered a new one.

    Indeed.  Bud Tribble's presentation on the new power management technology in Mavericks was one of the most interesting sessions at WWDC this year.  It's inspiring to see how deeply they thought about this (from hardware to software).

    I just went and had a look at that video upon your suggestion. Pretty good.

    I really like the idea of coalescing timers. With the extremely low power states Haswell has, it will be interesting to see the effects on battery life, more so on newer models than old ones.


     


    On the other hand Contacts, Notes and Calendar in Mavericks have all had the iOS 7 GUI treatment :( Calendar is ok but Maverick Notes looks like Mountain Lion Notes would look if it were on it's death bed (i.e. sickly). And Maverick Contacts just looks unfinished.


     


    I tried browsing to my ML partition to see if the old Contacts and Notes apps could be dragged across to Mavericks and used instead but there is a big "no entry" sign on the icon. For some reason they have disabled the older apps entirely. Since there is ABI compatibility between versions of OS X (since 10.4 I think?) I don't know why it is blocking these.
