The Tiger install went smoothly, and I've having lots of fun with the new features, particularly widgets and smart folders in Mail. I also ported all my RSS feeds to Safari, even though it's not my preferred browser. (It's too bloody stupid about pop-ups. Could I get a choice other than binary please? Yes-or-no is extremely annoying when you peruse many blogs with different commenting systems!) Now I just need to figure out how to get the stickies into the widgets, which I use mostly to keep the list of movies I want to rent from Netflix but don't want in the queue just yet.
I'm still testing third party apps. So far, all my Adobe software (non-CS) is perfectly happy (whew! from the $$ standpoint), and many of my other vendors have emailed with messages saying "download update here" or "you're jes' peachy in Tiger".
