WPF versions of Calculator, Paint, and WordPad in Windows 7
LiveSide and Long Zheng both have good reports of a user on Neowin who is claiming to have installed an early external build of Windows 7, the sucessor to Windows Vista. I haven't been following the Windows 7 development all that closely, but I was under the impression that Windows Presentation Foundation would play a more prominent role in this release than it did in Windows Vista.
