To many of the ppl that will read this they will not believe, but I am using 10.2 right now (August 2nd). I will not give away to much but here it is: New loading curser (Beach Ball) has changed to be bigger and sharper (but I think not as nice). New buttons, now a bit more flatter than the old ones. Instead of the arrows chasing their tails it has changed to a shockwave kind of looking thing. I tried iChat but I didn't have a AOL account and when I tried rendevouz it didn't work (Same with itunes, didn't work. The address book is cool but I can't get the "map of" to work. System Prefs have changed to be easier and look more modern (White mouse and keyboard now). Sharing prefs have changed to be more useable, you can now share printers and the internet, (So if you have an airport connection to an iMac you can hook another computer up to the iMac using ethernet to share the internet). New backgrounds, you can also set it to change every so minutes, hours etc. Mails new junk filter works really well. Dock has changed to a slightly transperant white instead of stripes. Preview has changed to be more complex with thumbnail options, and when you open more than 1 picture it doesn't open new windows for each, just shows them in the thumbnail drawer. If you use airport the menu bar thing has changed so you can connect using the drop down menu and you can see the time on the menu bar. TextEdit has changed, more complex. That's all I want to say and I will remove this post soon.
