I know Dan suggested I pm him with some illustrations of this, a while back, but I never did work out how to pm attachments.
So I'll leave these here. Basically, landscape is ridiculous, portrait involves too much sliding and scrolling and can't be resized, icons are mismatched (same on Firefox on my laptop) and members' info often takes up far more space than the actual post, which makes following a conversation quite difficult!
