I use a PC most of the time, a tablet pretty often, and very seldom my wife's smart phone. I guess it says a lot that I still much prefer a flip phone (just because it works better as a phone), it is so much tougher and great for my pocket when working in the garden.
The problem for me with the new format is the reduced width of the text boxes. I normally keep my zoom in Chrome set at ninety and at that the width of the text boxes are cut off on the right side, so you then have to scroll.
