I was not aware that phones, tablets, and watches were on the PC...
But on that note: the Surface tablet is considered the best hybrid PC in its class, and that includes Apple devices. The XBox has sold several tens of millions of units in each generation.
Oh, and here's the kicker: Microsoft's hardware is universally superior to Apple hardware in the same class. You can still use Microsoft hardware from the turn-of-the-century. Even Zunes still work (though you need to connect them as MTP devices instead of using the Zune Store). I have an HP Windows Phone that still works, and still handles call better than an iPhone.
I don't know anyone who still has an Apple laptop, PC, or other hardware more than 10 years old. Apple products simply aren't built to last more than a handful of years before they fall apart because you're using them wrong.
