LIRNEasia has been supporting app stores because we believe this is the solution that reduces transaction costs and mobilizes decentralized innovation. But as the NYT story today shows, it’s not an easy path for developers: Because Google makes its software available free to a range of phone manufacturers, there are dozens of different Android-compatible devices on the market, each with different screen sizes, memory capacities, processor speeds and graphics capabilities. An app that works beautifully on, say, a Motorola Droid might suffer from glitches on a phone made by HTC. IPhone developers, meanwhile, need to worry about only a few devices: iPhones, iPods and iPads.
