Here's hoping that it will not take a year from first public demo to final release. Tiger seemed to work pretty well at WWDC.
I would like to see a release of iLife 05 and this iWorks package immediately and allow any major bugs therein worked out in a month or so. Then, sometime in March, we will have the release of miniMac with Tiger preinstalled as well as refined versions of iLife 05 and iWorks. (Is that even enough time to find/fix bugs and have software preloaded on a new machine for shipping?)
Don't expect new Mac converts to like having an OS upgrade (free or $20 or $129) a couple of months after buying. That being said, I hate to see miniMac delayed any further awaiting software.
