there is a public outcry if a notebook runs only the latest version of Windows

The is no public outcry for the Acer Cloudbook I bought which tolerates Linux about as well as these new MacBooks.† Acer provides no drivers or other help. I don't see any reason to expect Apple to go beyond Acer to support unintended operating systems.‡

† It has trackpad driver problems, EFI mysteries, and a broken APIC (from Linux's viewpoint). With a couple hours hacking about you can get Debian installed, but each new kernel release is a crap shoot that can end in an unbootable machine for some as yet undiagnosed malady. Recent kernels result in it instantly deciding it has overheated and must power down immediately.

‡ I also don't see Acer submitting patches to my operating system, though that would be shocking.
