Many online pundits have taken jabs at the Google Glass heads-up display, but Quartz’s Simone Fox explains that despite Google’s marketing, the real audience for Glass is business. Fox spoke with two Explorers (early Glass adopters) who are developing inventory programs that could save manufacturers tens of thousands of dollars. Glass will also be useful in the financial sector — Fidelity Investments has developed Glass apps to monitor markets.

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-]).
