It's those who actually do need the power of a desktop that has me questioning Microsoft's quest for a unified OS. I don't even believe that the synergy between desktop and mobile is important to consumers.
I don't think consumers think it's important either. On the other hand, I really do think this is one of those things where you don't miss something until you've actually had it.
I've been perpetually behind the technological (consumer) curve in pretty much every field since about the year 2000. Out of all my friends I was the last one to get rid of my Nokia candy-bar phone (I literally had to hold the antenna with my finger at exactly the right pressure to get it to work) and that was when everyone was on iPhones and Android. I did get the first dual-core Android (LG G2X I think), but I only used basic features and got on Facebook only about three years ago. Twitter? No. Instagram? What's that? ... and so on... but when it comes to work I'm on-point.
Anyway, what I was getting to was that once I did decide to get more into a unified ecosystem I picked Microsoft because I was bored with Android, and once I got a phone that actually worked well and integrated in a way that I perceive as being close to seamlessly I knew I'd miss it if it was gone. I didn't know this when i had my Android. I had a Yahoo mail account and a third-party email client. Third party browser. DropBox. Etc.
So I think this could be similar in the sense that people might not seek out a MS alternative because it is a unified OS and it's the latest thing, but over time people might end up in it regardless due to their employers switching them over to such systems. I think it could be enough that your employer decides that since you already have a PC laptop you're now getting a Windows phone and a 'dumb' laptop instead... which will go with terminals at work that are now far cheaper (after all, they now don't have to pay multiple times for CPUs). And they also don't have to bother with storage issues and security. You've got your Lumia XXX and it is biometrically secured and it's your gateway to your cloud-stored data.
At
that point I think users may 'get it'.
Then it all of a sudden becomes less obvious to lug around a heavy laptop that's expensive when a thin cheaper one that runs off of your mobile makes much more sense. And why would I want to boot up a home entertainment system if I don't have to? I walk in the door and Continuum kicks in automatically and I just tell Cortana to start playing back ESPN or Netflix or whatever, as I place the phone on the charging mat.
I just think it's a matter of time. And to get all of that to work the smartest thing is probably a unified OS. The heavier apps I agree won't be affected, but I think it'll be more a matter of the average consumer leaving desktops and laptops behind and people like me still using them.
at the same time, the UI of Android (and iOS) is a lot more similar to Windows desktop than Windows phone's UI is to Windows desktop.
Sure, I'm of the opinion though that programmers probably are smart enough to take advantage of touch features and gui when it makes sense, and leave it alone when it doesn't. If I understand correctly the idea is that coding in UWP will allow apps to scale easily between screen sizes. So I would expect there to be no problem with a consistent gui. Really the only question is regarding legacy software, but then again I'm guessing again that they can retain their desktop-centric gui and that's fine. After all, if they're heavy enough to require that horsepower then they'll be inside computers that have keyboard/mouse attached to them anyway...
