Seriously? Do you not remember how slow Windows advanced until, say July 29, 2015? Prior to that Windows was nearly frozen in time after each release for years at a time. iOS advances extremely rapidly. But it's never going to become a desktop operating system like you seem to want.
The Air 2 did not have multi-tasking when it was released for review, it did not have an OEM keyboard, and it did not have a screen large enough to display two full sized Air 2 apps side by side. It's not a traditional laptop, but it's more than adequate for a LOT of people. But I bet you think you need a 15" MacBook Pro to post here and watch some movies right?
We are comparing iOS to Windows now? Compare it to another mobile OS - of Which windows 10 has only just become and will shortly fail to be! Android for instance.
Hmmm.... iOS has given the iPad Air 2 all of that now. Right? So the iPad Air 2 is now a laptop contender? No, it's an iPad with split screen - a really poorly implemented split screen that's currently for specific apps only and a chore to cycle through said apps.
I never once said iPad is not a perfectly good device for some people. I said I find it weird that a tablet running an iPhone OS is suddenly being compared to a freaking laptop / desktop or hybrid running full OS because Apple slapped "PRO" on the end and now that the Air has exactly the same iOS features as the Pro couldn't they theoretically do the same with that?
Maybe it's just me but I'm done with settling with whatever Apple thinks is just about good enough for the population.
Lets release a Pro product.
Lets not add maybe another port to that product so you could charge your phone whilst charging the product or have any other peripherals plugged into it.
Lets not allow extra viewing angles when the keyboard is attached. Leave that to third party.
Lets not allow pen storage and add a really daft way of charging that pencil - although not if that port is being used for something else like charging the device.
Lets update iOS for this product.
Lets not however change anything in that iOS to really make it useful for Professionals.
Lets make split screen really really hard to use and not allow two instances of the same app running side by side.
Lets not release any of our own Pro apps - Final Cut, Logic etc that could really make use of this Pro technology. Garageband, iMovie are good enough I suppose.
Let not make it possible for such a large screen to be split into 3 apps running at the same time!
