Something that has interested me recently with all of the "Web 2" activity going on is the area web based Operating Systems. I have stumbled across this one which seems to be in use mainly in Europe called "eyeos". Its a very simple operating system, if you can call it that, however toots a number of simple applications that are functional in a web browser. Who knows this could be the way of the future, but I think that it has a long way to go yet before it can replace the likes of Windows, Linux or MAC OS. I mean I played with it for a couple of hours to see what sort of functions I could perform with it and it runs quite well and doesn't seem to fall over, however the big drawback is the limited amount of applications for the OS. It comes with a "Notepad" style application as well as a few games and office applications, but every application had many shortcomings. I would have a look at it as it is quite interesting and as a web developer it is interesting the technology that is used to hold it together, but Ii think it has a long way to go before I trade in my current OS.
One other concern of mine in this arena is do I want my computer applications and data in the hands of a Company that cold virtually access my information at any time they want. Maybe I'm paranoid but I think you can see my point.
Take a look at the link below;
