SharePoint Team also shared more information about the SharePoint Server 2010 browser compatibility

Here are list of things to consider today to ensure a smooth transition from MOSS 2007 to SharePoint Server 2010

• Use 64-bit hardware for any new deployment. Deploying 64-bit is a current best practice recommendation for SharePoint 2007.
• Upgrade to MOSS Service Pack 2 and run SharePoint 2010 Upgrade Checker that’s shipped as part of the update. The Upgrade Checker will scans SharePoint Server 2007 deployment for many issues that could affect a future upgrade to SharePoint 2010.
• Get to know Windows Server 2008 with SharePoint 2007.
• Consider your desktop browser strategy if you have large population of Internet Explorer 6 users.
• Continue to follow the Best Practices guidance for SharePoint Server 2007.
