I always wished for myself and for the larger web community a 'Rock solid web based Open' Mobile Platform, and the change is happening very fast.
I fell in love with Ubuntu, with the 12.04 Release. Remarkable, well thought user experience.
6 months back, I switched completely to Ubuntu 12.04 and its my primary machine now. I'm blown away with their agile methodologies, love every small part of the web-integration and the Ubuntu software market.
Worth mentioning, Ubuntu Desktop is also strongly emerging as perfect web platform with tight integration with web-services. Many Developers are considering this as a strong open platform(as its web), and have started writing apps for ubuntu software market. So these apps should run seamlessly on Smartphones too.
The concept of HUD to search inside an webapps and navigate complex menu's is revolutionary! Worth mentioning, webapps are now exactly like native desktop apps; I recently used the Gmail webapp, it opens as separate app and we can search inside gmail. (They have an API to enable such HUD controls for any webapp).
All such advancements are only possible today, as we have faster Javascript engines, can leverage Cloud services, access to cheaper hardware and much faster Internet Penetration and adoption than ever before. The web can function as a strong platform by itself and not a hybrid model.
