Microsoft missed a massive opportunity to implement deep integration between Windows on the desktop and Windows phone. What I mean by that is a smart phone that become such an intimate extension of your computer that it blends into it during use.

I remain flabbergasted that today, in 2020, phones don't blend into desktop and laptop computers in any significant manner. I can't browse files on my iPhone X from my Windows 10 desktop through Bluetooth. There are band-aids and work arounds through apps and services. My point is that this should be a natural integration by now, not a pile of band-aids. To be sure, companies like Apple are at fault as well.

Think about everything you can do when you plug in a second, third or fourth monitor into your computer. You should be able to do that and more with your multi-core, multi-gigabyte, hyper-connected, high display resolution smart device.

I should be able to start a Zoom meeting on my phone, swipe the call onto my computer screen and back. I should be able to drop PDF and other files onto my phone by dragging them into the aforementioned native interface.

I still think MS have an opportunity to come out (again) with a phone that is a such a good extension of Windows that it would feel like you ripped the phone right off the Windows desktop and file system. The problem with this is it requires leadership and commitment they might not have.
