FTPOnline.com: An Expression of Frustration : "Last week Microsoft announced that the Expression development tools were probably not going to be available for at least another year. To many, that didn't even produce a blip on the radar. The Windows Presentation Foundation (WPF), upon which the Expression works, is scheduled to be an integral part of the Windows Vista operating system. To developers, WPF is a new model for graphics programming, meaning that it is also a new model for user interfaces. To administrators, it represents a new model of computing to support, one that requires new hardware to fully appreciate."
Happy news for Adobe, if accurate.
