This may seem like an off-topic thread so I'll put it here in the Lounge. However I think it'll help us get a feel for what displays we need to be aware of in planning future changes to the forum.
So how about it? What do you use to view the forum?
For myself about 80% is on two big honking desktops with 21 and 23 inch screens. About 15% is on a 15.6 inch notebook. Maybe 5% is on a 7 inch Android Tablet (Nexus 7.) I use Tapatalk a bit there but mostly I stick to Chrome. There's a mobile version of the forum that you can use in a browser and it's not too bad.
I don't have a smartphone at all and hence never view the forum that way.
