How to love your iPad again
Beginning with iOS 8 and OS X 10.10, Apple added an unprecedented level of integration between the two platforms. With subsequent releases of both iOS and OS X, this integration has become much better and more reliable.
While initially I found it hard to adopt this into my workflow - partly because I had kludgy workflows in place to try to make switching between the two work - I've found that once I'd gone through the process of starting something on my iPad and then switching the Mac a few times, it became second nature.
This is definitely a powerful feature, and once you master if, you'll wonder why you didn't use it before.
