I respectlfully disagree. Paul Thurrott who I trust to be an unbiased journalist wrote in his review: "Apple Mac OS X 10.4 "Tiger" is the strongest OS X release yet and a worthy competitor to Windows XP. Though it is marketed by Apple as a major release, Tiger is in fact a minor upgrade with few major new features for end users (though developers will be interested in some of the low-level work Apple has done with Core Image, Core Audio, and other technologies. That won't stop Apple fans from flocking to Apple Stores on April 29 and standing in line to buy it, even at its inflated $129 price."
WinFS, again, will ship some time later, after Longhorn is released. This is so for legitimate reasons, like to not delay Longhorn's release to public any further than Holiday 2006. I wouldn't personally want MS to announce a release some time in 2007, because then it may take another 12 months. They locked the schedule on December 2006 (as the latest). I read October 2006 on Paul Thurrott's website.
