The mystery of Mac OS X Leopard is no more!

Here’s a brief introduction of the ten main new features in this version from Mr. Qiao (out of three hundred), as follows:

1. **New Desktop** – The first feature introduced is the new desktop, which has an all-new top menu and a seemingly more attractive Dock. The main highlight is "Stacks," which helps organize desktop widgets. Stacks primarily serve to collect cluttered files on the desktop and are located within the Dock. You can drag files into them, and when you need to use/open these files or programs, simply click on a Stack, and it will display the items in a fan-like shape (actually more like multiple single-celled organisms connected...) or in a grid layout, allowing users to select what they want to open. Besides user-defined Stacks, Leopard will have a built-in "Downloads" Stack on the Dock, where all downloaded items will be automatically organized.

2. **New Finder** – Spotlight search now has a new sidebar with some slight visual differences (but not too many). However, once you press "Show All" (or open any folder), you might think you accidentally clicked on iTunes. The new Finder window essentially replicates the iTunes interface, including Cover Flow browsing, meaning it's almost like an "iTunes shell." Additionally, you can add smart folders to the familiar "library" sidebar seen in iTunes. Another feature is the "Back to my Mac" network search function, which allows searching and sharing files by tracking your Mac's IP address, whether on a local network or the internet. This requires a .Mac account for internet searches and also enables Spotlight searches.

3. **Quick Look** – Document preview functionality integrated into Finder, supporting most file formats. Although .doc files aren't supported out of the box, third-party plugins can be used. It's expected that more comprehensive file previews will be available through downloadable plugins in the future.

4. **Fully 64-bit Operating Environment** – This means that friends still using only 32-bit system Macs (including me...) will need to buy a new computer if you want to upgrade to Leopard! (Some MBPs seem pretty good lately!)

5. **Core Animation** – For those who remember, it's not much different from what was discussed last year. While this may not impress regular users, it's quite useful for developers (saving time and making fancy effects easier). The effects created with Core Animation can be observed in various new software applications, and it's said to produce some really cool interfaces!

6. **Boot Camp** – It doesn’t seem to have features that completely outdo Parallels. The only advantage is that it’s now built-in, so no need to install it via a CD anymore!

7. **Spaces** – Still the same four-grid virtual desktops, allowing dragging and dropping around; nothing much has changed.

8. **Dashboard** – Nothing particularly special, but the "web clipping" feature introduced last year remains just as interesting.

9. **iChat** – New tabbed video chats, ACC-encoded audio files, and a small Photo Booth effect for adding fun during chats. Additionally, you can share any content supported by Quick Look, even movies.

10. **Time Machine** – Just... backups! Additionally, you can use Quick Look to preview file contents, which is one of Finder's features.

That's it – overall, it's decent. Also, all versions are the same price at $129, set to launch in October.
