Semantic web anyone?

I would just love if someone could write once and for all a operating system which would work simultaneously with web. When I would like to participate to a meeting I could just click meeting on webpage and my computer, knowing that it is indeed a form of appointment, will pick up all the right information, and understand it enough to send it to all the right applications. Not to all Microsoft applications but to all devices.

I?am so tired to type calendar events to my Nokia, Outlook at office and Mozilla calendar at home. I have had this exactly same problem years and there hasn?t been any improvments. Actually I think it has got worse than it was few years ago. Few years ago Microsoft was promising in future all devices to work with Windows but today they say that all Microsoft product will work together. :(
