I love how easily everything works on my mac... I have a MacBook Pro 15", 2.33ghz.
Everything is so smooth, and I can do so much more than my old machine, but I think that's because my old machine was a piece of junk.
Reguardless, OS X is so sleek and sexy. I love how everything looks like it belongs for the mac, where in Windows all the programs all had their own unique and non-conformist look. In OSX, everything matches -- that's something I really like
In case no one has discovered it yet, Virtue is THE COOLEST application ever. It's like XGL for SuSE Linux and the new Multi-window thing for Leopard. I absolutely love it.
Not having a right-click is stupid, I think, and I really don't know why Macs STILL don't come with it, but the solution my macbook has for it is pretty nifty.
This is, I believe, the coolest computer ever
