Completely agreed on the aspect ratio complaint. 16:9 is good for watching widescreen video and lousy for everything else. I fail to understand how it's come to entirely dominate both phones and laptops in the last few years. Does anybody other than Apple make laptops with 1440x900 or 1680x1050 displays anymore?
I actually don't mind 16:9 on laptops so much because I tend to do a decent amount of movie watching on them -- that and the shape of the screen has little to do with how effectively I can use the interface.
