In the mobile software world, developers are considered vital to the health of platforms, of which they have several to choose from. Platform owners have to work very hard to make sure their SDKs and tools are easy to use. Too much friction, too little documentation or too steep a learning curve can drive developers away. Which platforms are the easiest to develop for?
On desktop computers web apps have come to dominate many application categories. They are easier to develop and deploy across multiple platforms and it’s possible to iterate much faster. A very large number of developers would like to be able to apply the same technologies and techniques on mobile devices but very few are able to do so successfully, particularly for mass market consumer apps. One of the most important reasons for this is performance. Resolving this issue is much more about politics than technology.
