Took them long enough. That this will happen was obvious to anyone (feature parity and all), but that it will take so many years is baffling. Wait, actually no - Apple has been extremely slow and clunky on ever increasing number of aspects. For example, that you can step into Apple store and buy some overpriced, pathetic and outdated products like Thunderbolt Display, Macs with multi-year old specs (but the same high price as when introduced!), the ridiculous upgrade prices, memory prices and so on and on.
Don't know about you, but the last years have been a steady disillusionment for me. I already use as many platform agnostic services as possible (Dropbox for files, Spotify for music, Google & Microsoft productivity, Kindle for books and so on), so that I have freedom to switch away if I decide. Android is very good these days and I love my Windows 10 gaming PC. I switched to everything-Apple in 2007, but maybe around 2017 this expensive experiment will be over for me. My last hope is that this year's Macs, OS X 10.12 & iOS 10 will be so amazing that they make me reconsider all this...
Sorry for the rant, these feelings just been piling and I wanted to finally say something.
