On one score, Yahoo has been extremely receptive to an offer from Microsoft. With its Yahoo Messenger for Vista, the Internet company has been one of the few consumer software companies to come out with a Windows Vista-specific product.
The instant messenger program doesn't have a lot of extra features (in some cases it has fewer than the generic Windows version). What it does have is an extremely pleasant look and feel. Using the Windows Presentation Foundation graphics engine built into Vista, the program smoothly resizes Windows and moves buddy icons around based on the screen real estate available.
