X vs XP

As a recent Mac convert, I’d like to throw some google-juice in the direction of [X vs. XP](http://www.xvsxp.com), a well-researched and well-presented site comparing OS X and Windows XP. As well as presenting a modestly unbiased opinion, it’s also amazing resource for learning about some of the things I’ve been wrestling with on OS X, such as “how do I tab into drop-down menus?” (impossible to navigate [xe.com](http://www.xe.com) without this ability).
