Yesterday Apple released Safari 4 Beta, and with it introduced some new UI changes. If for some reason you wanted to revert back to some of the old UI (Tabs not on top), there are some hidden preferences which can be edited via the command line.
Typing in strings /Applications/Safari.app/Contents/MacOS/Safari | grep DebugSafari4 in Terminal, outputs a list of preferences that can be configured:

DebugSafari4TabBarIsOnTop
DebugSafari4IncludeToolbarRedesign
DebugSafari4IncludeFancyURLCompletionList
DebugSafari4IncludeGoogleSuggest
DebugSafari4LoadProgressStyle
DebugSafari4IncludeFlowViewInBookmarksView
DebugSafari4TopSitesZoomToPageAnimationDimsSnapshot
DebugSafari4IncludeTopSites

Personally I missed the blue progress bar and was hoping to get it back. By typing in defaults write com.apple.Safari DebugSafari4IncludeToolbarRedesign -bool NO and defaults write com.apple.Safari DebugSafari4LoadProgressStyle -bool NO, then restarting Safari brought back the blue progress bar.  However, it also puts a loading spinner in the tab, which honestly forced me to revert back to defaults.

For those of you who have been waiting for iLife ‘09. It looks like it will be shipping tomorrow for $79. A family pack (5 Licenses) is also available for $99. If you purchased a Mac on or after January 6th, you can upgrade for $10.

Tomorrow is Apple’s final Macworld and I will have updates and thoughts throughout the day. A quick rumor roundup can be found here. I’m really looking forward to tomorrow, though I can’t say that I am excited about the idea of a new 17-inch unibody MacBook Pro with a non-removable battery. What new Apple products are you looking forward to the most???
