I would offer that a weekend is enough time to determine if one has the time necessary to devote to learning to switch to OSX.

I'm a *NIX user. I have been for 20 years. I use the 'vi' editor, as for the first several years, it was the only one I was exposed to (barring more primitive ones). I would love to learn the 'emacs' editor, but I lack the necessary time to devote to making the switch.
