Highlighted features of Mac OS X 10.7 Lion Preview
Many Lion features are borrowed from iOS:
- Launchpad – iOS style app launching and folder management
- Full-screen apps
- Mission Control – Encompasses Dashboard & Expose as a super window manager
- Gestures & animations – extensive multi-touch support
- Auto-Save
- Versions – built-in version control of all documents, in an interface similar to Time Machine
- Resume – saves your Macs last state after reboot, all apps, sites, and documents included
- Mail 5 – very similar to Mail on iPad
- AirDrop – instant wireless document transfers
- Lion Server – now built into Mac OS X Lion, no longer a separate OS
The Developer Preview requires a 64-bit Core 2 Duo processor or newer, and you must currently be running 10.6.6 in order to download the preview release.

I don’t want to run beta OS, but does anyone have the wallpapers? I found the lotus but I want the mountain and others. Anyone?
Lol, I came here to ask this as well.
I know I’m not the only one, I will post links when I find them, someone is bound to upload soon.
I am tempted to buy a developer account just so I can run the preview. Is it stable? Any word?
It’s a developer preview, so expect things to be stable enough to use but buggy enough for it not to be a public release.
Anyone can register to be a Mac Dev for $99 and then download and install Lion Preview.
Or just… you know… not pay, then download it for free from darker crevices of the web like everybody else.
