It may come as a surprise to you, but there is a free, built-in RSS reader in Windows Vista. Haven't noticed it yet? It's the feed reader that's available in Vista's Windows Live Mail. Windows Live Mail utilizes the Internet Explorer 7 RSS feed store in Windows Vista. The Windows RSS platform takes this "Common Feed List" and intergrates it into Windows Live Mail. This means that any feed you subscribe to in IE7 automatically appears in your Windows Live Mail, too. The feeds are displayed in a separate tab in Windows Live Mail, which makes it easy to switch between your feeds and your email. Since your feeds are in Live Mail, you can take advantage of the "Search Folders" technology to make custom folders for your feeds like "Flagged Feeds," "Unread Feeds," etc. Non-Vista users can get Windows Live Mail here. Thanks to the Windows Vista Blog for this tip!
