Office 2007 One year later Where are the killer V

At the Consumer Electronics Demonstrate final January,Office 2007, Microsoft and Yahoo made a major deal out of a Vista-optimized version of Yahoo Messenger that was supposedly one of a large number of compelling Windows Presentation Foundation (WPF) apps within the pipeline.On December 6, 1 year later on, Yahoo introduced a pre-beta of its Vista instant-messaging app. And nonetheless no word on what took so long or when Yahoo will obtain the final edition available.What provides? Aren;t applications supposedly what promote an working system? If that's the case, where would be the must-have Vista apps constructed to take advantage of the Windows Presentation Foundation (WPF) graphics, the Windows Communication Basis WCF) communications and Windows Workflow (WF) underpinnings of Vista?Microsoft Customer Platform Technical Evangelist Tim Sneath has been cataloging “excellent WPF programs.” With Yahoo Messenger, he is now up to 16. Sneath;s list doesn;t include several household-name software developers (other than Yahoo and Roxio). Nearly all of the apps on his list are custom business applications.Is WPF too hard to write to? Is there insufficient positive payback for optimizing for WPF? Over on the istartedsomething.com blog, Lengthy Zheng wonders aloud:“1 of the main roadblocks for WPF applications has long been performance and it looks like this application (Yahoo Messenger) suffers the same fate. On a dual-core technique with a more than plentiful graphics card, this application can’t even render the emoticon popout opening and closing without obvious pauses. Generally when anything animates, CPU usage flies right up and performance hits rock bottom.”Or maybe it;s the fact that the real tool suite for writing Vista applications — Visual Studio 2008 — only was released to manufacturing some weeks ago? Developers attempting to write to WPF, WCF and WF, until now, had to use some stop-gap tools from Microsoft to take advantage of these new Vista technologies.In January, I posted the question: “Exactly where will be the killer Vista apps?” One 12 months after the Vista launch, I am wondering again: Exactly where are they? Anyone know of any new programs coming that will make Vista more compelling to consumers and/or businesses?
