In my experience, I found it difficult from time to time to do certain thing, but when you dig deeper you almost always find that the hooks you need and the functionality you need is already there.
I come to think that the Django team must have the Guido's time machine. If you need something, take a good look, the solution might be under your feet.
I think that cdnjs is really a great idea and I use it for my new projects. To Google becoming a javascript CDN is far from there core business, I think a distinct entity is much better suited to become the global javascript host.
I was a long time linux user too. I switched for the quality of the hardware and because I was tired of fighting poor hardware support.
For me a Mac is a much better experience, you focus on your work, the hardware/OS just work. No more fighting with XF86Config, broken wireless driver, and a hardware market focused on bringing the cost low instead of improving quality. If you look at how much time you spend on a computer, the cost is not the most important factor. When I get back to a pc, it always hit me how much the quality is inferior, but then I think about the cost pressure to sell a laptop at 400$ and I undersand.
What I don't like on Mac, is that I feel as a just another follower of a cult, yes the look is good but I think I would prefer a less flashy brand.
