The wife and I have Windows, Apple, and Unix machines networked. They all play well with each other.
When we want to do real work, we use the Apples or Unix machines.
When we want to....uh....er...battle Outlook or twaddle, we (reluctantly) engage the Windows units.
Oh, forgot, Microsoft’s Solitaire still rules.
The new Apple Pro (starting around $3000) looks like a coffee pot or a small trash can.
Different strokes for different folks. My experience is the exact opposite. Oh, I like my iPhone just fine. I use my iPad a lot for surfing and some neat apps. My MacBook air is also nice but for the same price my wife's Lenovo Yoga with Win 8 and a touchscreen beats it hands down in specs, speed, usability etc. At work? Still using Win 7 with a dual monitor system and happy with that, too.
