I couldn't disagree more. The mobile user experience would not be improved by having multiple web browsers, and my life as a developer would be a lot more annoying trying to support multiple mobile web experiences that differ significantly (otherwise what would be the point of alternative browsers.) If Apple were to disallow alternative browsers on OS X, that would be disastrous. But OS X is a general computing platform. iOS is not. It is a device first and foremost. It does not need to be an open platform where any developer can do anything.
