So here we are. Windows 7 launched and it isn't like the whole world changed. We knew it wouldn't. Snow Leopard launched with much less fan fare, but it brought some changes that someone needed to make. A fully 64bit OS that focuses on multi-core technologies as well the disposal of the Power libraries that permeated the Darwin landscape. Windows and Macintosh will be battling this out for many years to come. What changed with Linux? With the latest release of Ubuntu we saw some major changes. Things have become more tightly integrated, flashier and heavier.
