I would add built-in support for .pdfs to that list.
That is a much better suggestion that #10 - Desktop Cube (Linux, PC-BSD) - which is strictly a novelty.
I don't think that needs to be part of the operating system, as it can easily be supplied by aplications, many of which are free. You can easily add freeware viewers, and if I remember correctly, OpenOffice is thinking of adding the ability to create pdfs as well.
On another note, I think Vista is coming along. I recently bought a laptop with Vista, and it seems to work just fine. Of course, it helps that this laptop has 4G of RAM -- Vista uses well over 1G just loading up and sitting there. But, given the resources, it does perform. Its still early, but I'm beginning to believe that MS botched the introduction of Vista more than the system itself by trying to convince people it would run on the last generation of hardware. Remember the "Vista Ready" and "Vista Compatible" stickers which have led to some class action lawsuits?
