This is using Microsoft Word on a big screen monitor using the Lumia 950 more or less as
a CPU. I need to find a document. The folder is empty
Anything on this device? Documents. Well, it feels smooth. It doesn't feel sluggish. One has to say that
It doesn't feel like the device is underpowered at all. Everything is working fine. Here is what using Microsoft Edge via Continuum
looks like. Apparently, mobile processors have become powerful enough to produce, to make desktop work comfortable and convenient
Let's see what Facebook is like now. It's not fully optimized. You still see the narrow vertical view of the app showing up here
Let's have a look at the news feed. Ah, that's me. Yay, I'm going to be famous. Okay, can we see what Twitter looks like
No? We can't open that app here. We are working to support more apps for now. We can open this one on your phone

Twitter being one of them
