I have a retina MacBook, and i bought a Surface Pro 4 for my wife. While my initial impression of the Surface was good, we just have had endless issues with the Surface (we are not the only ones: Microsoft issued an apology for Surface Pro 4 early adopters). My wife also prefers by far her iPad as tablet over the Surface Pro. Actually, she was even thinking of returning it, and buy a MacBook, although she is a long time Windows user. Alas, we were outside the return period. If the Surface had worked out well, I had been thinking of changing to Windows myself, as a long time Mac user. I like the concept of the Surface in principle. But Apple just has some magic in terms of quality and user friendliness that is hard to replicate. So, I'm staying with Apple.
