I see what Tim Cook is getting at. Tablets are the future.
With that being said, it will be a while before tablets become powerful enough to adequately replace notebooks and desktops. And it is not about processing power, it is all about the OS. It does not have to run Mac OS X, apps just need some massive updating. Apps like Pages, Keynote, and Numbers (iWork) need to be updated to be more like they are on Mac OS X. Same with Photo's, it needs to become more like it is on Mac OS X. Photo's on IOS needs features like RAW image processing and editing, as well as the full suite of tools it has on Mac OS X. Mobile apps shouldn't and do not need to be stripped down, dumbed down versions of desktop software.
Also 'PRO' Apps are needed to really call this a professional tool. Build Final Cut Pro X, Motion, Compressor, Logic Pro X, MainStage and not just dumbed down versions, but fully functional and capable versions.
Besides the OS, there are three really important things that need to happen hardware wise. First is more internal storage, like 256GB, 512GB, or even a 1TB storage option. Also replace the Lightning Cable with a USB 3.1 Type-C Port, and give it the ability to use external hard drives for storage and backup, as well as other abilities that USB 3.1 Type-C bring. Lastly, the Apple Watch and iPhone both have 3D touch and Force Touch, that seems like a major omission from the iPad Pro.
With the inclusion of these features and change, I would be extremely interested in the iPad Pro. In fact I would probably buy a 1TB Cellular iPad Pro in Space Grey if these changes were made. I would replace my 15" Retina MacBook Pro, Samsung S34E790C Ultrawide Curved Monitor, Harmond/Kardon Sound Sticks, Magic Keyboard, and Magic Trackpad 2 with this. I would probably even go for a 1TB iCloud Storage Plan with this. I would even repurchase Final Cut Pro X, Compressor, and Motion on IOS.
But until these changes are made, this is not the iPad 'Pro' its just the 12.9" iPad. I am excited to see what the future holds for this device, but until then I am happy with my 15" Retina MacBook Pro. Here's to hoping for future version with Apple A10X Processor, 8GB of 2133MHz LPDDR4 RAM, up to 1TB of Internal Storage, and 3D Touch. As well as updated suite of apps, and the addition of 'Pro' Apps.
