I don't know if Nokia has something on the code that will stop others from making phones that can run the software. If they do then I think that Tizen will get a lot of angry customers from Nokia, these customers are very devoted and Samsung and IBM is getting a fast start. QT is going to support Tizen and I think it just is a recompile and all apps får Maemo will work
a good battery is required for that ram and cpu ... i would like to use maemo for lets say ... till another thing like maemo comes up
