I'm anxious for the update. I have noticed some glitches and have had to restart a few times (or was too impatient for the computer to work itself out of a mess). QT7 impresses and discourages at the same time, nice H.264 stuff, why does it now need to flatten a movie when saving off the web?, kind of jumpy, and I hate that little launch window. The only way I am able to open anything into Adobe CS is by launching the app and then selecting the open menu. I can't double click, go from iPhoto, drag to the dock icon, etc. Overall Tiger seems nervous, being way faster at most things but then hanging and thinking for a bit way too often. I have had to quit the dock a few times. My networking seems unstable and moody. I can't print to my network printer. Oh and still since 10.2 in column view if you arrow down a list and then shift click away from where you landed it doesn't select the range. You need to click on that item and then shift click away. Also open a window and make it look like you want, close it, open it up again, it views differently (like icon view instead of column view). The best fix I have for this is open a window, change it to column view, RESIZE IT, close it before navigating, open it again and it keeps. I like dashboard but the widgets seem too stiff in a lot of ways like the Fed Ex tracker isn't wide enough to show the time of each line of info but I can't resize the window or text. Also, with a medium or small screen those widgets get very crowded very quickly, we need an expose of the widgets feature. Overall I am very impressed with Tiger though.
