What Leopard/Intel stuff have I missed?

Time Machine, FTW!

I know a thing or two about backups at the enterprise level. And nothing, nothing, anywhere on any platform comes close to what Apple is able to do with Time Machine. It works inside the applications. You can pick and choose precisely what you want.

And anyone who’s ever been burned by lost/corrupted data will tell you, if you’re not backing it up, then it ain’t important to you.

Yes, Time Machine is a huge deal and a great tool. If you don’t have an external drive that you use for backups, get one and turn Time Machine on.

Spaces is also quite useful if you have applications open often.

Spotlight has been much improved, to the point that I no longer use a launcher application such as Quicksilver.

Both great answers, but I was thinking about 3rd party apps more. Apologies for not making it clearer in my first post.

Most the apps I’ve found are Universal. I got my first Mac machine six months ago; I got a MacBook Pro.

If you check www.osx.iusethis.com, you will have a great resource for almost any app you’re looking for. Unfortunately, I haven’t found many apps that are Intel exclusive.

Alas, I have not gotten time machine to work for some time, I got all the way to the Apple engineers and they were having me reinstall everything from scrathc which isn’t worth it for me.

SuperDuper! all the way.

Leopard only things…
Spaces for sure is a huge thing for me.
Quicklook-pressing spacebar to quickly preview pretty much any type of file
Bootcamp-cool for games

and of course, www.osx.iusethis.com
this is a nice site also www.opensourcemac.org/
