A 3.5 inch screen, which is what on the iPhone, is nothing to sneer at, it's actually pretty large. However, it seems that most competing phones nowadays use a screen size of 3.7" (Nexus One, HTC Incredible), 4.1" (the new Dells), or 4.3" (HTC Evo). Especially after using an iPad, I feel like it wouldn't hurt to increase the screen size by a half an inch or so. Do you guys agree, or do you think 3.5" is already perfect and anything larger would just be a waste of space and a portability sacrifice?
