Time they are a changing. For some, these changes have already taken place. For others, they are pushing back and sticking with their existing development plans. Microsoft is certainly pushing a different approach / model for those of us who have made a living customizing and building on top of SharePoint. I for one do prefer this new model for many reasons I try to adopt it where it makes sense. However it does not work for everyone and every situation. Part of this is due to the implementation of the model (it’s still relatively new), part is due to breaking the way we have all been thinking about customizing and extending SharePoint for over a decade.
