    The iPad Pro's battery is pretty massive @ 38.8Wh (iFixit). In contrast, the Retina Macbook's battery is 39.71Wh (iFixit).

    The Retina MacBook comes with a nice 29W charger though, compared to the iPad Pro's comparatively measly 12W charger. So far it feels like a giant step backwards in terms of charging time :(

    Did you expect it to charge the same speed as a 29w charger or something..? Find a 6A (30W @ 5v) charger and it'll likely pull closer to 20w I bet. It has a built in throttle that limits the current it can pull. For ex. the iPhone 6 came with a 1A charger but can pull something like 1.5A off an iPad charger (even though the ipad charger is 2.4A).

    I thought the original iPad 2 had 42Wh battery.

    iPad 2
    25 Wh

    You're thinking about Gen 3 & 4. They had 43 Wh batteries

    Based on the reports I'm seeing here Apple had two target customer types, graphics people using the pencil, and Senior Citizens that will love the big icons and readability. They'll sell a lot to the senior community.

    This argument confuses me.

    I hear all the time from (older) friends and relatives that they would opt for the larger device because "they want bigger text".

    Explaining resolution independence to them is basically impossible.

    Do you mean they would prefer how the larger screen allows them to zoom larger than would be possible on a smaller screen?

    Even if that is the argument, surely the Air 2 provides plenty of room for seniors/the poor sighted?

    Perhaps I'm not getting the right information. I haven't see one.

    Other posts I've read today, (several sources outside of MacRumors) are saying the icons are slightly larger and the text is slightly larger. Is that wrong info?

    As far as I can tell, everything renders exactly as it would on an iPad Air 2.

    Also Schiller mentioned at the keynote that it was designed so that the width of the iPad Pro had exactly the same number pixels as the height of the iPad Air 2.

    Thus making it possible to run two "full sized" (though really slightly squeezed) iPad apps side-by-side in landscape mode.

    Though I may be wrong!

    That would be interesting if it could do that. AFAIK, lightning is currently limited to 12 watts maximum. Apple should've went with USB-C on the iPad pro. Would've been able to charge twice as fast.

    That is very possible it's limited to 12w. In that case, it won't help to use a higher wattage charger, obviously.

    Too bad lightning is only 3 years old. It's probably too soon to move away from it. I'm sure they'll go to use type c in the next 5 years.

    Exactly. Customers are going to throw another fit when Apple does eventually move away from Lightning to USB-C, just as they did when they moved from the 30-pin to the Lightning port. Too bad USB-C wasn't around when the iPhone 5 came out.

    My guess is that the iPhone 8 will use USB-C. I doubt the iPhone 7/7S will. If for some reason the iPhone 7 does use USB-C, we could see it on the iPad Pro 2.
