I agree that they totally FUBARed the Spotlight windows. It was soo usable in Tiger i could easily jump to categories and find what i wanted but in Leopard its just a big unorganised Finder window of search results. I have no clue what the hell they were thinking.
Front Row is also a step back for all the reasons mentioned in the thread.
Finder still struggles with networking
The 3D Dock is ugly
I still think they could've eased off a little on the Greyness of UI elements. Its too dark IMO
Stacks was abysmal but thank God they mitigated that
Drivers for GPUs seem to really suck. Since even the most powerful graphics cards seem to be struggling with animations
Its a good OS, its faster, more powerful but they simply should've have left somethings as they were rather than changing them for changing sake
Maybe a lot of others like the changes, your opinion alone doesn't mean that Apple jacked up Leopard. Although I do agree with you about Spotlight.
