So apparently on Mac OS X it's a bad idea to do lots of heavy disk I/O if you want to continue interacting with the UI ( Read more... )

The Apple Blog: 7 Lion Annoyances

The only two items from this that bothered me were Dashboard as a space (rather than an overlay) and "All My Files". All My Files is useless for me since I have thousands of documents (javascript, web site design images, css files), automatic backups, etc.
