LINA

Have a look at LINA. It's a really clever idea - it solves the same problem as Java tries to solve: making all operating systems equivalent using a virtual machine so developers won't have to support multiple platforms. But there's a difference: LINA doesn't require the developer to work with different tools than he is used to, such as the Java compiler, because LINA is linux. Also, there will be a large amount of software available for it from the start, again because LINA is linux.
