Only if, in 9, they provide the option to ditch the 'Start Screen' when dealing with apps, especially for workstations.
Careful now, that's tantamount to heresy for some on this forum. Some will be very unhappy:
Not heresy at all :>. My point has been that you basically have A Tale of Two Interfaces. The Mobile Interface and The Desktop Interface. You can run The Mobile Interface easily on your system, simply hit the window key, select Start from charms, etc. Once there, knock yourself out in The Mobile Interface. That doesn't go away.
However, if you choose The Desktop Interface... then it includes the ability to run both Apps and Applications(with the option for them to be windowed). Apps will be denoted with icons, same as .exe Applications(give them a little RT moniker in the upper left if they want). And they'll adhere to all the rules of the desktop, and when you close out of them you land on the desktop.
So you can choose either The Mobile Interface(hi, i'm on a tablet!) or The Desktop Interface(gonna party like its 1995!).
Both choices should be equally valid, and neither should bleed over into the other. Pick your poison. You should also be able to access the Windows Store from the Desktop, and when you add apps it adds them to both The Mobile Interface(as a tile) and The Desktop Interface(as an icon).
