I was a solid proponent of OSX for all development. I've only had to go through 2 macbooks in the better part of a decade, upgrading the OSX versions along the way ... and so, when it was time recently to buy macbook #3, I was actually a little sad that Apple's slipped so much recently and I had to go with an Asus zenbook (of course gutting windows 10 and running Ubuntu :-) Its running great, with none of the issues I was having with Mavericks.

yes, I would've liked to stick with Apple & OSX. no, I don't feel I could and still be as productive as I need to be.
