Hurry up and Wait:

Oh Boy, Lion's available. Uh oh, this download is gonna take a while. Turns out you're not the only one waiting for Apple's update. All your friends have been waiting patiently to download the update and even if Apple every server in the world hosting the download, it would probably take a while. So start the download and go grab yourself a delicious meal or watch a movie. Don't worry, Lion's features don't expire, they'll be there when you get back.

Switch the trackpad back:

If you've been using a MacBook for a past few years, you're probably used to the two-finger scroll. Well Apple decided to switch it up so it works like the Magic Trackpad. Up is down, down is up, it's madness. Navigate to System Preferences/Trackpad Scroll & Zoom tab. Uncheck Scroll Direction: Natural. This will return trackpad scrolling back to what you're probably already used too on your MacBook.

Speaking of trackpads gestures:

Apple added a bunch of fun new trackpad features to Lion. While you''re in the Trackpad system preference, check them out with along with fancy videos showing you how to use them. Take a few moments to learn these. It'll make Lion just that much better.

Where's my HD?:

If after installing Lion your Mac's HD, and any attached drives, have dissappeared from your desktop don't freak out. If you're the kind of person that needs to see their attached drives head to the Finder.

Navigate to Finder>Preferences in the menu bar. Click on the General tab and just check what you'd like to see on your desktop.

iChat supports Yahoo chat now:

If you have friends that are still using Yahoo messenger, you're in luck, iChat now supports Yahoo's instant messenging system.

In iChat head to iChat>Preferences Click on the Accounts tab. Click on +. Select Yahoo from the drop down and enter your information.

Where's Bounce Email at?:

If you loved the Bounce email feature of Mail half as much as we do, you're going to need to sit down for this one. The feature is missing from Mail in Lion.

Search the Internet and Wikipedia from Spotlight:

If you're a fan of iOS's seach web and Wikipedia feature, well guess what? You can do that in Spotlight on your Mac.

Clean Up By vs. Sort by:

You now have the option to either Clean Up By or Sort By. Clean Up By arranges your items once. Sort By keeps your items arraigned via whatever method you choose.

AirDrop:

AirDrop is a great way to quickly share files. You can find AirDrop in the sidebar of Finder windows. Just click on it and suddenly you're a working the RADAR station of your Mac. Just drag and drop, and you're sharing a file.

When you're presented with an incoming file you can choose to Decline, Save, or Save and Open the file. All files are saved into the Downloads folder.

Full Screen! Uh oh, now what?:

You have two options head up to the top of the screen and the Men Bar will appear. Go to View>Exit Full Screen or press Control+Command+F to leave full screen mode. This same key combo can be used to place a compatible app into full screen mode.

Floating Definitions:

Look up words and get a floating definition. Right+click on an word and choose Look Up "word"

That's a fancy definition box.

Lion Tweeting:

You can right-click on text and select Tweet to push the text to the official Twitter app.

The app doesn't even have to be open. It'll launch the app for you.

Open from preview:

Clicking on a file, hitting the spacebar, and having file enlarge and become visible is one the greatest things ever added to OS X. It's the polar opposite of Ping, that's how awesome it is. Well it just got cooler.

You can now open said file by clicking on the Open In button in the top right corner. Great when you're quickly looking through a series of photos.

Preview Sites from iChat and Mail:

Someone sends you a link via iChat or Mail. Before you would click on it and wait for your default browser to load.

Now you can hover over the link and a little arrow will appear to the right of the URL. Click that arrow and you can preview the site before loading it in Safari. If the link is to your liking, you can Open the link in Safari by clicking the button in top right-hand corner.

Right-Click Email Attachment :

Finally! You can right-click a file or folder and select "New Email with Attachment" Mail will open, create a new message there's your attachment already placed into the message.

Auto Save Is Awesome. But...:

But, only work with applications that have the feature built in. That Photoshop document you worked three hours on, yeah you should be saving that along the way.
