Just out of curiousity: Why does the above "Apple's" in the article pull up a sponsored ad?
VERY good article. I ended up getting Tiger with the purchase of a new Powerbook, so the price of the upgrade wasn't too much of a concern. Others in my department are more reluctant to purchase it, however (even on their incredible NIH-funded budgets). For the 10.3 crowd, Tiger doesn't offer a whole lot more in usability than they already can accomplish.
My advice: If you've already got a Mac with 10.3, don't fork over the money for Tiger unless you really want the newer features. If you're getting a new Mac with it installed, however, enjoy!
