At the end of the day, these blades are about maximizing screen real estate and offering an efficient, haptic UI. In much the same fashion that a physical qwerty pad outperforms the on screen keyboard for word processing, blades would facilitate other extreme user input endeavors.
I think Microsoft could leverage Windows RT further on this front.
I’m a big fan of multiple monitors on my desktop. Many of the Application I use have extremely complex UIs. So, when using AutoCAD for example, I can transfer some of the UI elements onto a second monitor to maximize the drawing area on the first. Without the second monitor, the various screen elements encroach upon each other.
This situation can become even more cluttered as other applications are opened, each with its own UI, each potentially used in continuous support of each other.
The processor and memory resources of the Surface Pro could meet the challenge, but the screen will be the limiting factor. Used as I described above, the necessary screen changes would be strobe like. Docking into an additional monitor would be quite gratifying.
What if Windows RT allowed the devise to be used as a second monitor? It could not actually host any of the x86/x64 applications, as the hardware specs to not allow it, but it could certainly contend with UI elements.
An Autodesk app could be fired up on the Windows RT devise to allow me to host the UI from AutoCAD – currently running on my desktop or Surface Pro. Autodesk may even provide a blade for AutoCAD or Inventor, or all of their other applications (similarly, Microsoft with Office-Visual Studio , Adobe . . .). The Blade serves as the constant UI, the screen of the Windows RT devise would be the volatile, context sensitive UI.
Both Windows and Windows RT communicate so that the RT updates the UI based on which Application is active on the Pro version (obviously, the blade wouldn’t change but the RT screen could).
Say this were all possible, now the additional cost of the Surface 2 can be adjusted to consider the saving as would be incurred with the purchase of a second monitor. This efficient package can easily follow the user around from office to home or any other place where a second monitor would be useful.
