Perfect Mobile Platform

What would make up the perfect mobile platform? What characteristics should it posses? Here are some of them, in no specific order:

• User Interface/Experience - a rich user interface that provides a great user experience. When using the phone, everything should come naturally, with ease, and should have the WOW factor that makes you never want to leave the phone out of your hands. Doing common tasks should not take more than a few clicks. 
• Application Ecosystem - Having many applications to chose from is not as important as having quality applications, those that satisfy a particular need, like finding a place to eat, checking your email, or playing Doom. Integrating location, social networking, and sensors is a must.
• Internet Browsing - surf the Web from anywhere, on the go. A mobile browser should be able to render pages properly and fast, navigation should be done with ease, data should be compressed as to save bandwidth, and use the latest web technologies (HTML5, CSS, JavaScript, etc).
• Battery Life - it better not leave me hanging after a full day of use, or in the middle of a call, or while searching for a place to eat using the GPS. 
• Development Ecosystem - provide a rich set of APIs that can access all the features of the phone, and can provide the best user experience. Provide tools that can be used to make it easier to write apps. Publishing an application should not involve much hassle. 
• Openness - here I refer to not only an open and free platform, but to a platform that allows any mobile technology to work on it.
• Enterprise - features such as security, integration with email/calendar/notes/contacts servers, messaging, to name just a few. 

There is no one platform that satisfies all these needs better than any other platform. What is needed is a platform that has the user experience of iPhone and Android, the application ecosystem of iPhone (and Android very soon), the internet browsing of iPhone and Android (mostly any WebKit-based browsers), the battery life of the Blackberry, the development ecosystem of Android and iPhone, the openness of Android, and the enterprise characteristics of Blackberry. 

Will we ever have such a platform? I really doubt it.
