Back in the 1980s, Apple didn’t design products in house, but instead turned to design firm Frog, then called Frogdesign. Frog founder Hartmut Esslinger has released a new book, “Keep it Simple,” that features pictures of a number of forgotten Apple prototypes from that era. The Verge has posted some of Esslinger’s photos, including prototypes for cell phones, tablets, and laptops that range from the ludicrous to the downright prescient. 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-]).
