No killer feature for Mac OS X Tiger

Apple previewed yesterday Mac OS X Tiger. I haven't watched the keynote but from the description, it does not contain a killer feature like Expose for Mac OS X Panther.

The enhanced search engine, Spotlight, or Safari RSS may be interesting but I don't think it is worth the price of Tiger when it is released.

All in all, that is a good thing that there is nothing I want badly from Tiger: I just got my PowerBook with Panther and I'd prefer to skip a release of Mac OS X. I'll keep my bucks for Mac OS X.5 (whatever its name is!).
