While this isn't the link of the day, this is a great article on Mac OS X. It is written from the standpoint of someone who is a unix user (specificly BSD). It's nice to see people looking at OS X as something different then your typical Mac OS. Existing Mac users will still have issues with it. But that is to be expected. In many cases you're asking them to change how they've been doing things for years. I actually think it was pretty cool for apple to make the drastic a jump.
