Hi, Google offers some great online tools, blogger, Docs, Reader, Picasa, YouTube and more.
They are now introducing an operating system on netbooks in 2010.
I think this is great news for education as I posted in my blog yesterday. http://mjpageeducation.blogspot.com/2009/07/google-operating-system...
I think it is potentially good but is going to have great trouble getting in the door. The biggest problem I see is the reliance on advertising. I don't know how schools will like having ads fed to their student computer screens constantly. Say what you want about Windows but it is controllable to a very large degree.
There is also, of course, the fact that so very many teachers are not tech-savvy and are, in fact, not just resistance to change but completely negative about it. I've tried sharing little free aps and those have been shot down. I can't imagine trying to sell a whole new OS!
