The Surface Pro 2 is getting things closer to that day.
And it is a failed device bringing us closer to the day when Microsoft files for bankruptcy.
My question is why have two OSes when one can do it all?
Thats what Windows 8 tried to achieve, one OS to rule them all. But you always have to make compromise. When you want both, you will lose a third thing. If you want a Tablet and also USB ports to connect all the old peripherals never designed for mobility, than your battery life will suffer. If you don't create something like AirPrint and make it the only accepted printing method on tablets, than you need to provide drivers for all printers out there. This will bloat your OS and kill the storage space in your 16GB Surface. So you will need to go with 32GB as minimum and loose your price competitiveness. You can create a squashy Touch Cover keyboard but it will never be as sturdy as an actual laptop, which now has kind of the same price as your hybrid device. Any true power user who actual needs the capabilities of a laptop will always go for a laptop and ignore your frankenstein experiment.
Plus tablets are only replacing laptops for people who never truly needed a laptop in the first place.
Thats the majority of people in the world. The same people who never truly needed a desktop.
That doesn't necessarily mean that all tablets should be made specifically for people who don't need anything more. The form factor is too useful to relegate it to the role of glorified Facebook machines.
iWork apps are free with all new iPads. That doesn't mean they are or will ever be desktop-class applications. Touch input limits the precision with which things can be selected and screen size limits the number of selectable choices. These are limitations of the form factor itself.
People have been able to buy desktop replacement laptops for years now.
And they keep complaining about no dedicated graphics and no upgradeability because they still misunderstand what a laptop is. Its not a desktop to go, it has its own form factor limitations.
Remember, simplicity isn't about removing features. It's about designing it so everything is intuitive and easy to come to terms with.
But mobility is about removing features, reducing everything to the minimum core of what you need to preserve the most basic functionality together with battery life. Thats what a tablet is and why it can't be a laptop.
As long as the underlying complexity stays out of the way for your average user, but is easy to access for people who need it, then no one's losing anything in the process.
Simplicity also means that you can not mess up the system no matter what you try to do. Higher complexity comes with more possibilities for failure and misunderstandings, which is the opposite of simplicity.
It can still be simple enough for Grandma to pick up and play with it, yet deep enough for power users to get things done with it.
Grandpa is still smart enough to detect complexity where ever it hides and play with it till its broken. Power users always only want the best and thats more like a Mac Pro. Power users settle with less mobility in exchange for more power.
But there are things tablets can do quite well that they're not doing well right now. They don't currently, as in right this very moment, have the hardware or software to do it.
I don't know, maybe the A7 together with iMovie is already good enough to render movies. But it will never be the very best device to do this kind of tasks. As long as fingers are bigger than pixels mouse pointer will always be more accurate than touch screens.
I don't see why we should sacrifice potential for the sake of grandmas. Yeah, they deserve their simplicity, but they're not the only ones who deserve to have their computing needs taken care of, simply because there are more of them out there than there are 3D artists, painters, or movie editors.
All your higher computing needs are already taken care off by said desktops. The computer development began with fulfilling higher needs and is propagating into lower needs, finally coming down to people who only need them to update their relationship status on Facebook.
