Users of the latest beta can synchronize their bookmarks on multiple computers as well as browser preferences such as homepage/startup settings, language and themes.
Additionally, you can also now install and use Chrome extensions in "incognito" mode.
Finally, the beta release "contains the goodness of some new HTML5 features, namely Geolocation APIs, App Cache, web sockets, and file drag-and-drop capabilities. Additionally, this is the first Chrome beta that features initial integration of the Adobe Flash Player plug-in with Chrome, so that you can browse a rich, dynamic web with added security and stability -- you’ll automatically receive security and feature updates for Flash Player with Chrome’s auto-update mechanism."
