In both cases, what is unusual for Microsoft is the positivity the gizmos have generated. Fair or not (and I'd argue probably not), Microsoft isn't expected to blaze new trails and develop hot new products that have the potential to create new markets or shake up existing ones. We know Microsoft's history - too early with tablets, too early with smartphones, too early with wearables - and this generates a degree of skepticism around what it does. But with HoloLens and Surface Book, much of that cynicism seems to have evaporated.
Desktop operating systems (Windows, Linux, OS X - all of them) are in a pretty piss-poor state right now for various different reasons, and in the case of Windows, I find this truly sad because Microsoft seems to be doing some really cool stuff in the laptop and tablet front. Sadly, the software just isn't up to par.
Much like the Apple, we can hope 2016 brings some major improvements, but considering Microsoft's endless promises and failures to deliver, I'm not holding my breath.
