Stability has been rock solid for me, and my poor little Mac Mini get very heavy use all day every day...
Quicklook is probably my single biggest favourite feature, with screen sharing a close second.
I haven't been able to get Back to my Mac to work either

One more addition to the ugly: Apple has some serious issues with copying over the network. In Leopard, extended attributes (EAs) don't get cleanly copied over which means that applications which rely on them (like Skim, the best PDF reader and annotator bar none, open source and free of charge) cannot work with network volumes.
Even worse, backing up across the network (LAN or WLAN backup) will not back up EAs.
Leopard has other networking bugs that were ironed out only late in Tiger's dev cycle. Leopard has some serious under-the-hood problems and my experience has been similar to Dan's in that Leopard is less stable than Tiger. In some ways, actually, this isn't saying much because Tiger never ever seems to crash.

One big "ugly" that your missing is that Leopard Server has serious permissions problems when sharing to windows clients that didn't exist under Tiger Server. This is still true under 10.5.2. Also there is a very bad bug in iCal that deals with the calendar cache that makes subscribed calendars a major pain. I have a work around posted here:

But having to run an automator script on a schedule, well, stinks.

I've been using a Mac since System 7 was brand new, and have updated my system software with each new major release. Tiger marked the biggest improvement with the most innovation. Leopard, while it has its strong points, is the most disappointing OSX release (the garish default desktop should have been our first clue). It marks the first time Apple has traded elegance for eye candy, and worse.
Can you say DRAB? The folders are drab, the color scheme in general is drab and clunky, and some of the new graphics are big and clunky. Even worse, some of Apple's poor design choices are not customizable.
On top of all that, Apple still hasn't figured out Finder window management, and if you ask me the Find feature user interface still needs some work.
C'mon, Steve. If you've given up on elegance, at least give us some redo options.

I totally agree. There have been times in dealing with Leopard that makes me think they hired a bunch of Windows developers to build it.

I should state that I do like a lot of things in Leopard though. Networking is much easier now.

Right now we're having a heck of a time getting it to connect to our Active Directory network. (As if it's important?) When are they going to fix this? 10.5.2 was supposed to fix it!

[JScott]

our Macs have been working great in our AD environment since 10.4. Perhaps something in your AD setup isn't right. I'd be happy to give you any pointers I have. Send me a PM and we can take this one offline.

I disagree that Spaces is a letdown. I use it since day one and I am in love with it. It works really great, at least after the 10.5.2 update. Before there were many problems with apps not appearing on the right space, finder password windows not being displayed, etc..
Now, everything works really great and especially on my Macbook I can organize my applications in a nice way.

[Ciguatera]

I disagree. I love the new look of the Dock, the 2D is to simple, it just isn't MAC anymore. MAC lives on eye candy! You can go back to beige if you want.
Second, Spaces is super useful for me. I have may apps open at once so to keep my desktop from becoming a mess, I just have them open in different spaces.

[petvas]

I also find the new 3d Dock better than the old look and I absolutely love it. I wouldn't go back...

As far as the stability concerns, Leopard 10.5.2 is as stable as Tiger and runs faster! Before the 10.5.2 update stability was a big issue.

I just had to change a setting in my Linksys router and Back to My Mac works perfectly.
However, I've been unable to do video chats on iChat with friends on different cable systems. Skype works fine though.

I now backup everything because of Time Machine without doing anything other plugging in an external drive. This is quite the nice bonus even if it's as boring as insurance is.
I like the better Airpot Utility. It was a mess in Tiger.
I like partitioning on the fly.
Bonjour. Yes. I can now use a printer over my Airport Express network that I couldn't use with Tiger.
QuickLook is quite nice except I think it will be much nicer if they ever make it compatible with Stacks.
I also now like the new Finder sidebar. I got used to its small font too.
I got used to the new look too. And now like it better than Tiger. It's a little more serious and professional look. It's weird, but I briefly went back to Tiger a few months back and I thought the folder icons in Tiger looked a little cartoony and not as sophisticated as Leopard's.
Mail too seems to work better. I didn't use it much before and I forget exactly why, but a few things bugged me. Now I'm slowly using it more and more and I like.
I also use Spotlight as an app launcher for those apps not in my dock.
Stacks is nice especially for a folder with about 24 icons in it. I just like the nice large and easy to read type with that many icons. So an option to limit the size of the stack grid and have multiple pages would be nice.

1) Leopard does not automatically remember folder view settings. If you change the view for any folder, like from icon to list view, then every folder you open afterwards will display in that view. To make Leopard remember view settings for a folder, you have to manually edit the View Options for each individual folder. This is nothing more than a kludge. Leopard should either always remember view settings, or provide an option in the Finder to remember view settings for each folder.

2) When Time Machine backs up to a network volume, it uses an expanding disk image which increases in size as more items are added. The problem is that the disk image will not automatically shrink when items are removed. This can be a problem when multiple Macs are backing up to the same network volume. Time Machine should include some kind of maintenance function to recover free space from a backup image.

3) Although the Finder now allows more flexible file permissions to be set, there is still no way to enable automatic permissions inheritance. For example, suppose you have files on a Mac that need to be editable by a group of people who use that Mac. Right now, only the person who created the file can edit it. There is no way to set up a shared folder in which everyone can edit the files in that folder. You have to manually reconfigure permissions on the folder contents every time someone creates a new file. Apple's "solution" is to buy Mac OS X Server, which is hardly a helpful solution for someone using an iMac or a laptop.

4) Spaces would be more useful if you could set a different desktop picture for each space.

I agree. The actual experience of the parental controls is frustrating. Portions of the parental controls work well, but there are problems with loss of connection after nearly any change, and things are filtered even when explicitly allowed. Still waiting for this to get addressed and fixed.
