LOVE and HATE Leopard
I've upgraded to Leopard on my MBP 17"/2.4GHz and I have mixed feelings about it.
Things I love now that I have Leopard:
1. Quick look - I love being able to view my files without having to open them.
2. New iChat - I love being able to SMS, multiple account sign ins, and being able to share or control a desktop
3. Spaces - When it works.. I LOVE it
4. Spotlight seems a little more responsive and quick.
Things I HATE now that I have Leopard:
1. Sluggish or non-smooth animations/transitions with some features. Specifically: The dock (magnification, genie effect, and stacks), Spaces, . It's very choppy or sluggish, where as Tiger was very smooth. When you have a fairly new Apple computer (mine is only a couple months old, and was the most expensive configuration for a Macbook Pro), you expect that Leopard will run smoothly and quickly on it. That is NOT the case, and it's very disappointing.
2. I HATE HATE HATE the stacks feature. They removed a very useful feature of Tiger, which was to be able to drag a folder into the dock, and then be able to navigate to any part of that folder, from the dock. With stacks, you CANNOT view all the items in a folder, and if there is a sub-folder (like many apps that install themselves in their own folder within the applications folder), you can't get to the contents of that sub-folder without having to open up a separate finder window. This was a HUGE step backwards in my opinion. They should have at least offered the ability to have this feature available.
3. Spaces is a great feature, but doesn't feel fully cooked. It's temperamental, and doesn't work sometimes. Sometimes I can't get to an App in a certain space.. and I have no idea why. Also, the expose feature of spaces does not run very smoothly.. it feels sluggish.
I love Leopard, but at the same time, I hate it. BUT I don't hate it enough, to go back to Tiger. I just hope a patch addresses these issues, and I hope it comes soon!
