When I tested Monster Connection on an Android (just for fun, to check the performance) I noticed something weird. The UI was tiny! Not at all like in the preview on my PC. I scratched my head, wandered back to my computer, and realized I had designed my test UI for an iPhone 3GS resolution of 320×480, while the Android I tested on was at 800×1280. “Well, duh, of course that doesn’t work.” But that moment, when you realize how many resolutions and aspect ratios there are, you get a little scared at first.
