I would quantify that: "Software badly designed for too large of a screen might not work on smaller screens. Software badly designed with a hardware keyboard in mind might not work on the onscreen keyboard." Semi-earnest question: I don't understand why fragmentation on Android is apparently a massive downside, but on iPhone and iPad it's suddenly a great opportunity. Are the different resolutions not fragmentation? Can the iPad not use an external hardware keyboard as well as the touch keyboard? Is compass-less iPhone 3G being sold alongside the 3GS not fragmentation? Will the AR apps work?
