Just been helping a friend try to decide which phone she's going to go for between an iPhone 4 and HTC Desire HD. An immediate difference between the two is their physical size. The Desire HD's 4.3" screen dwarfs the iPhone's 3.5" screen, but I noticed the iPhone has a much higher screen resolution. Am I right then in thinking that means you're able to fit more onto the iPhone's screen than the Desire HD's, despite it having a smaller physical screen? If that's the case, what advantages are there to having a big ass 4.3 screen if the resolution's a little lacklustre?
