Received an iBook for my mother today. MacOS X is quite sweet. Lots of eye candy. The benefits of an OpenGL powered UI. Even groovier of course is the fact the it is BSD under the hood. A fact made perfectly clear once you launch a terminal or look at the process list.
I would certainly be very tempted to get a Mac if I couldn't find a decent laptop to run Linux well. My business partner is trying to run FC2 on a Dell D800 and having "issues". I want a Laptop but don't want "issues". And I most certainly do _not_ want a Windows laptop. An Apple at least would be a Unix box. I could run lots of Unix apps..
The Gnome guys could do worse than copying Apple when it comes to user experience.
Not overly impressed with Safari though (aka KHTML + Apple UI). Apple should have used Gecko for their HTML component. Firefox and Safari share many UI similarities.
