It’s been 4 days now with the new cat… so far, so good.
Right off, there’s a noticeable performance boost in startup, shutdown and general Finder tasks. That, along with the 7GB reclamation of disk space makes Snow Leopard worth the price.
The new QuickTime is slick, but lacks the export features of the previous version of QuickTime Pro. Thankfully, Apple anticipated this disappointment, and put the old QuickTime in the Utilities Folder in Applications.
Some folks will undoubtedly be using older applications which require Rosetta to run. Again, Apple found an elegant solution for those who chose not to initially install Rosetta. When starting an older application, a dialogue box appears asking if you’d like to install Rosetta. If yes, then your system connects to an Apple server, downloads and installs Rosetta, and launches your application. Pretty close to hassle-free.
There are still a few software developers racing to make their applications play nicely with Snow Leopard, but most of the major developers are already on board.
The Snow Leopard upgrade is highly recommended.
