Apple’s iWatch is nothing more than a rumor at this point, but Google Glass, Google’s smartglasses that can take pictures, record video, show you incoming text messages, give you directions, and much more, are real. Glass isn’t quite yet available, but Joshua Topolsky of The Verge got a chance to try out the current beta. His money quote? “But what’s it actually like to have Glass on? To use it when you’re walking around? Well, it’s kind of awesome.” follow link
Go Back and Forth Fast in Preview
If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.
The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).
