For some reason, I feel like Microsoft is yelling at me when I look at the all caps menus:
A cursory review of the menus reveals that there appear to be a few things that make life a little simpler for us developers. For example, Create GUID is already in the tools menu. No need to add it (like in previous versions of Visual Studio):

Adding a content type was fun. I was surprised to see this handy little content type designer:
This is, of course, nice because it asks you what content type you want to inherit from and creates the XML - including the Id - for you:
There is obviously a lot more to explore but overall, my initial impression is positive. The product is continuing to evolve and become more mature.
