I'm not sure what the obsession is to bring desktop apps to windows rt/arm.
Windows on arm is not meant to be a productivity OS. Who in their right mind is going to sit down and try to use a windows desktop app on an 8 or 10" tablet?
Sure, I can see a very small % of power users that would love to bring their favorite apps along, but this does nothing to improve Win tablets for consumers. What is needed is a better app market on Win 8. Once enough developers are building quality apps for Win 8, then suddenly a Win RT type of tablet makes a lot of sense to most consumers. Allowing arm desktop apps will not solve that. Besides, why not allow it to remain a walled garden and keep it more secure then a standard windows environment could be thanks to its more open nature.
Reading through this thread, it seems clear that some people simply want MS to go back to Windows 7. They don't want anything to do with Metro and believe MS should not be trying to cater to other markets beyond the traditional desktop OS. Well if that happened and MS were to get rid of Metro and just focus on evolving the desktop os from 7 (so lets say just take the desktop side of 8), MS would be fairly steadily walked out of the market thanks to the pc decline. They become the next IBM and you guys can just all move on to the next cool thing out there.
Of course, that might not be a smart move for MS. If they want to be a devices and services company, then they need a strong consumer presence. That means they have to address the changing landscape when it comes to what people are using. There is a shift away from a traditional pc and a move to tablets, smartphones, and ultra portable laptops. We can moan and groan all we want, but the reality is that the vast majority of pc users are finding that they no longer need to buy a pc to get things done. That is related to the fact that they simply aren't doing complex things with their pcs. A desktop environment may always be needed, especially in the enterprise sector, but consumer interests are changing and it doesn't seem to be slowing down. Despite what some might say, the desktop is not going anywhere and MS has made that clear. They don't intend to remove the desktop, just to create a transition option for those users that are embracing the touch environments of tablets or smartphones.
A few notes regarding 8.2:
So that leads us back to Win 8. No, I don't think the answer is to remove Metro, but rather keep improving it. I think that 8.2 should bring with it more customizations so that the user can choose to say disable the metro ui outside of the Start Screen. 8.1 already adds much of that, but I'm sure some would appreciate more control. They should continue to make tweaks to the desktop, although to me, the desktop is so mature at this point, that is not a whole lot they need to do, just work on bug fixes.
8.2 also needs to continue to mix the metro ui with the desktop side in smarter ways, such as allowing for pinned shortcuts to metro apps on the desktop, and possibly some kind of windowed mode for apps. They also need to keep improving the multitasking behavior, as far as how the snap modes work. I like the changes in 8.1 to allow more control over the size of the snapped view, but they could do more.
8.2's biggest goal though should be to improve the Metro UI. That means they need to going over every aspect of it and looking for ways to improve productivity and bring in more desktop-like features where it makes sense. Again, 8.1 is doing some of this with the inclusion of a file manager and migrating the rest of the system settings, but they still have much more work to do to make the Metro side a mature environment.
They need to build on the app store improvements in 8.1 to make it as easy as possible for developers to get their software pushed into the market. They also need to keep improving the apis so that developers can make the most of Metro and not feel limited functionality wise. MS needs to aggressively court developers of a wide range of content, from productivity apps to games. The bigger their library, the bigger their user base.
Finally, they need to finish the job of bringing Windows Phone, the Xbox 1 and Win RT/8 under one OS roof, meaning a shared app marketplace and a shared design/ code base. That way, all platforms can feed off of each other, with developers suddenly getting access to a much larger audience without much effort, just making the UI tweaks needed for particular devices.
Metro is a 1.0 product, something like iOS 1.0 or Android 1.0. Even MS is unable to avoid that reality, so that means it will take time for the software to mature. As long as MS is really focused on improving it, I don't see why it can't mature and become a fine platform going forward. The desktop environment can happily remain in Windows even as Metro matures. Again, this isn't about MS trying to kill the desktop. They will keep that around as long as there is demand for it, and there is plenty of demand.
