The Start screen doesn't look like it's changed much, but there are three new default apps that show off the possibilities of Windows 8: Travel, News, and Sports.
Microsoft recently has promised that Adobe's Flash plug-in will work in Internet Explorer 10 Metro by the time Windows 8 is finished, but it wasn't ready when we used it.
Windows 8 Release Preview comes with protoype trackpad drivers to allow people to use multitouch gestures on their trackpads. It's a big, long-overdue step forward for Windows.
In the new Sports app, semantic zoom powers different layers of content. Zoom out from the main view of your favorite teams to see different categories you can then zoom back in on.
We know that Microsoft plans on ditching the translucent Aero borders for Windows 8 Desktop mode, but that hasn't happened yet. The company hasn't said what will replace it, yet.
Splitting the screen for working in two apps at once isn't new to Windows 8 Release Preview, but it works much better than before. You can also see the new Mail app layout here.
