We've already hit this subject more than once. I wish I had a dime for every "I don't see anything special in Tiger" threads.
Well let's give you the crib notes version.
Quicksilver is nice but it won't pull out metadata in your files to the specificity that Spotlight will. Spotlight indexes on the fly. Modify a file Spotlight has tracked that modification. Quicksilver can add this via the Spotlight API but you're vastly confused if you think QS can do what Spotlight can.
Dashboard- Nicer than Konfab to me but it's not what has me jazzed about Tiger. Even though you're wrong. Dashboard creation is "MUCH" more flexible than Konfab widgets.
Automator is much cooler than what was shown at WWDC. Since then we've found that it doesn't just use Applescript but can use Shell Scripts and any languages or frameworks supported by xcode. Once you save scripts they show in in the menu of the app using the script. You launch the script and it works without Automator even needing to be open. This was shown live in the WWDC video. That is "Services" on steroids people.
iChat AV is an excellent way to showcase the power of the new AVC codec
Core Image/Video- Taking something that takes 10 seconds and making it real-time should get anyones attention.
.Mac sync built in. Now any developer can easily write sync features into their apps and with tiger they know it'll be there because it's systemwide in the OS now. Perfect for those that have laptops and desktops.
Spotlight- is just huge. I really have to laugh when I hear people bring up QS or Launch Bar. Those are studebakers compared to the ferrari that Spotlight is. I guess many people will just have to use it to fully grok what's going on.
Right now Tiger PR is for developers. There's no need in going into anymore detail because if you're not a developer you won't understand the ramificatios of new Apple tech in Tiger.
Suffice it to say you "will" want Tiger when it comes out in 6-9 months. You haven't even seen the %90 of the features of Tiger yet. By the time it ships it'll likely contain Quicktime 7, OpenGL 2.0 and bunches of little features and fixes that make you smile.
Remember before people started using Panther they were NOT enthused. Panther had one visible feature and that was Expose and until people actually used Expose they thought it was useless...just like Dashboard.
