I think I really need to update my 10.5.1 to 10.5.2 because from the article I recently read, It contains some attractive things and support more "Apple things" like remote disc and wireless time machine using time capsule. Here is some sneak peak for 10.5.2 update I taken from babygotmac.
- Remote Disc Support
This is the new feature of macbook Air because it has no optical drive. Remote disc settings has been added to 10.5.2
- Wireless Backup
Time Machine can also use a disk connected to your Airport Express as a backup location. Maybe this can support Time Capsule for backing up file wirelessly
- Time Machine Dropdown Menu
You can drop off Time Machine icon on your dock because now there is one on the dropdown menu bar.
- List view in Stacks
I have written some information about List view in Bahasa Indonesia. But you can see the picture below
