Chrome OS, would it be good enough??
If you haven't heard the rumors (press releases), Google plans to release it's own OS by the end of 2010, according to the news it's going to be aimed at smaller devices (laptops/pdas etc.) and is going to be focussed on web-based functionality including the ability for people to write plugins (it was compared to facebook here) for it so they could customise it.
Just curious as to who thinks they'll be using it instead of their current OS and whether you think it'll be a worthy rival to Windows or mainstream Linux distros?
