When Yahoo Messenger 9 was released last month, I was a little disappointed. I had seen the previous videos about the special yahoo messenger for vista. Since another "normal" version of Yahoo Messenger was released before the Vista one, I thought Yahoo has forgotten about the Vista-special version of its messenger. But Yahoo today released a preview version of its Yahoo Messenger for Vista.
The Yahoo Messenger for Vista does not have all the features that are part of the normal yahoo messenger since its only a preview. The highly anticipated voice chat, video sharing and file sharing (using Microsoft's Silverlight) seems to be missing from this version, which was demo'd at the CES. Also, its taken Yahoo way too long to release even this half-baked version.
The Yahoo Messenger for Vista is actually meant to showcase the bling-bling using the Vista specific graphic capabilities as well as other Vista components like Sidebar. A lot of people have been complaining about the slow performance of his version. Long Zheng says that Vista SP1 might improve the performance of the WPF that this version uses.
