Why is 16:9 Suited For Traditional PCs But Not Tablets?

This is a weird top for me, one which I don't understand, why 16:9 is suited for traditional PCs (laptops and desktops) but not tablets.

What I see that the problem stems from is people think that a tablet is a different computational device altogether from a laptop for example and should be used differently.

I made a post a while back stating that due to the bezel differences on Windows tablets, they are often a smaller width/height ratio then a lot of 16:10 Android devices. This was met with ridiculous comments from people who didn't read what I was saying and jumped on board saying I should be comparing screen sizes not devices sizes even though I was tackling the point of usability of the device.

That was a different thing though, I never stated that the screen following the ratio of 16:9 was the best just that when placed on a device with universally sizes bezels provided the same experience as most 10" android tablets even though it had a wider screen.

This post I am going to tackle whether 16:9 is actually usable for a screen on a tablet in the terms of software usage not hardware usage.

My first thought was, yea, 16:9 in portrait looks pretty weird compared to 16:10 or 4:3 but then I thought, why are we even using a 16:9 Windows tablet in portrait mode.

The whole point of Windows tablets are not to be tablets in the sense of your Android or iPad but to be a tablet that runs Windows. Why are you using it in portrait mode. Tablets are no longer a separate thing to laptops, they are the same category of devices when it comes to Windows.

So when we are thinking about using a traditional Windows laptop, it is always used in Landscape mode. Why would we all of the sudden take the laptop screen and turn it sideways and use it as a tablet. Why would the instinct be not just to pick it up and use it in landscape like you have for the past twenty years.

Disregarding the fact of whether you can hold a 16:9 Windows tablet in your hand, why would you even consider using a Windows tablet in portrait mode when you never have before in the form of a laptop.

This isn't really a topic of whether 16:9 suits portrait or a tablet it's more of a, why would you consider using Windows in the first place in portrait mode even though you haven't done so with any other form of Windows before.

I would like to hear from you guys why Windows tablets are being used in portrait mode even though we have never done this before? And what makes tablets different from laptops? Are you going to say a Surface Pro isn't a laptop? It's internals say it is and it does everything a laptop would so why would you not consider it a laptop? Why does the fact that it has no keyboard mean to should use it in portrait mode?

These are just some thoughts on the usability of Windows tablets, I would be interested in hearing what you think.

Thanks for reading :D
