I love the comments here and elsewhere... MS sets the price of Windows 7 around or a little lower than the price of Leopard, and everyone makes smart remarks about "no family pack" and "it would cost $4 bajillion to upgrade my houses 8 family computers". I feel sorry for MS now... even when they do something nice, they're still wrong.
Comparisons to Snow Leopard are particularly unfair... If you don't pay the full price for Snow Leopard, you paid the full price for Leopard! How is that actually cheaper again?
Not to mention the fact that Apple can freely move costs among its hardware and software because they're selling all of it, for example charging more for RAM and less for OS X. MS has to make the money on its software.
