Talking about Something before they have it
I find it amusing that Microsoft still, after the failures of Vista start marketing their products before they've actually made them.
The same went for WinFS among others which then hurt the company more by them not delivering what they promise.
Microsoft needs to unveil a product as they have some to a stage where they feel it just about works. The reactions would be much different if they weren't just talking about it, but were infact going to release it in a few weeks.
