Start looking for alternatives...
Well when it turns out that Window 8 is a failure and when MS pulls their head out of the sand and realize it is because of the drastic and unwanted changes to the desktop, they might be forced to change course.
At this point however they are still in denial so of course the current plans for the next version of Windows is going to follow down that same flawed path. It doesn't mean someone smart inside MS with influence can't wake up at some point and help to put Windows back on course. As I said, it's just a service pack and some egg on their face away from being fixed.
