    Anyone heard anything on when we can preorder or will it just be "boom" here it is?

    I want to CTO the better CPU and was hoping the preorders would let them arrive at or near release day.

    There isn't any. Looks like we won't be able to order until April 10th. Which is a shame, because I too am getting the 1.3GHz and now this means we have to wait another week.

    I'm not sure how much the CPU upgrades are going to be, but going from 1.1/1.2 to 1.3Ghz is a negligible difference that you will not notice in day to day tasks. For me it's not going to be worth the probable $100+ Apple are going to charge.

    There is a disproportionately greater difference in the max turbo, speed, though. How well that can be utilized remains to be seen.

    I wouldn't call it 'much greater'. The ratios are listed below:

    1.1 to 1 2 upgrade:
    1.2/1.1 = 1.091 => 9% better
    2.6/2.4 = 1.083 => 8 % better

    1.1 to 1.3 upgrade:
    1.3/1.1 = 1.182 => 18% better
    2.9/2.4 = 1-208 => 21% better

    Fair enough - say disproportionately greater. And there are questions such as whether it's better to take a little longer at a slower clock speed or do a task faster at a higher clock speed in terms of heat buildup in a fanless design. :confused:

    Yes, there is a lot of unanswered questions. It probably depends a lot on what type of tasks the computer is doing. If it can get done quickly enough the faster turbo mode is better.

    ----------

    I'd like a specification on energy efficiency of turbo and non turbo modes.

    There are a few apps that I unfortunately need to run in parallels, so I need as much as I can squeeze out of this little 5W part. :)

    Me too. Parallels is a must for me.

    How does the "turbo" speed work? Does it just kick in when necessary, or is it toggled by the user?

    I'm also interested to know this.

    Edit: Apparently when you run an application that requires extra power this happens. It's an intel thing.

    I can easily see the Core M processer doing very well for the short bursts of computer processing power that my applications demand. It's funny that Intel just came out with such a processor now. It may have worked earlier too.

    Will there even be a CTO? Looking at what they have on the Apple site now, it looks like there will be 2 models, one with slower CPU and 256 GB SSD, and the other with faster CPU and 512 GB SSD. Kind of like how they sell tablets and phones.
