Bigger is superior. Hopefully you can use the full screen or two apps at once while R/W content. Beginning with the original gangster note which was huge for it time
Now it would be average. But it also had 16:9 which I really like since most phones don’t use that today.

My main concern is the interaction between OS and QWERTY. Still haven’t heard anything about that.

But then, for sailfish, you don’t really need a nice/big screen becouse you can’t use it with any nice services anyways.
