Yesterday I installed Snow Leopard. Here is what I liked:

 

  • Exposé in Dock
  • Minimize to the same icon instead of adding extra icon to the Dock
  • Loads and in general works faster
  • Remembers language settings for each application. Now I can type in Russian in Skype, in Latvia in the web browser and in English in NetBeans without using language switch

What I did not like:

 

  • Safari plugins lost
  • huge icons in stacks with no way to make them smaller
  • PHP 5.3 and no way to downgrade to 5.2.x

It took 1 hour 15 minutes to update my MacBook Pro. In general it was a good update.
