I'm not ruling EEE out, but this move feels more like "staunch the bleeding" to capture more developers and retain the ones they have. I'd love to read a leaked Powerpoint or memo that explains the long-term strategy here.
I think this is a great move by Microsoft to be able to EXEC a competitor's binary files natively. But, I think it risks being an admission that Win32/64 syscalls and Windows file system semantics are a crufty boat anchor holding developers back. To admit that risks inviting more developers to bail on Windows.
