Hi Tachi,
I just upgraded to OS X and so far have been happy with it.
There are somethings to get use too...
*downloading files I can no longer rename them prior to the download.. at least when using Safari.. I have not used Internet Explorer yet since the upgrade
*I miss collapsing the windows, and I hate the dock and the fact that you can not use the apple menu anymore like I use too.
*cool thing is setting up mulitiple accounts so I can log in and when anyone else logs in they do not have access to my book marks etc etc
*MPEG's play the best now on here, and Quick Time Player handles them fine. If it will not play AVI's, you can find an AVI to MPEG converter at download DOT com
*Install 10 right over 9.1 -so all your old programs will open in Classic mode - will run 9 inside of 10
BACKUP ALL YOUR FILES PIOR TO DOING ANY INSTALL
-good luck
