As we all know there is things about OS X that you REALLY appreciate, and is one of the main reasons you love OS X. Then when your forced to use windows (or another OS) you REALLY miss that feature. Some for me are: Expose -- this in IMO is the #1 reason why OS X is great, expose is the greatest thing about OS X, it's so flightning fast, so responsive, so easily useful. I use expose like a million times are day, expecially with hot corners. Any who has problems with ahving lots of windows, i garuntee you, if you get into the habit of relying on expose you wont be able to go back. Another thing, I dont know the name of this features but it's handy, the ability to highlight anything, and drag it into mostly anything. when using windows i miss this so much. I mean, I got a block of text i highliht it, then drag it into an MSN window... or I drag it to my desktop and OS X automatically makes a file for it. I just LOVE that convienence. OS X is built as such a rock solid core, it can even make bad software seem good. Recently I was using a beta of some software, and at the time it was pretty bad software... BUT OS X still made it great, I mean even a simple application still has tons of features simply because OS X is that way. I just love how simple OS X is, no matter what your doing theres an easy way to do it. If there isn't an easy way i cn bet ya you can download an applescript from the internet that will do it for you easily. Really... Apple has OS X to near perfection... now with leopard I can't think of anything this OS cant do that i'd want it to do.
