u checked them out and yet say that "Nobody knows if it will be released as a windows or not " ! . It is a research OS and some of its features will make into future Windows releases but never as a major version OS. I will say the same thing again, people use Applications and Vista already lacks a lot of apps that ran well till now hence it will be sometime for it to take the lead till all those and other apps make people to upgrade. how then a completely new OS without any apps will make a major release ?  dont talk about the ram consumption when the software itself will never be released or wait for it to be released. criticizing something even before it is released or something that is still being researched on doesnt give a good impression
