Apple’s new Mac Pro relies completely on external ports for expansion, with six Thunderbolt ports, four USB 3.0 ports, one HDMI port, and two gigabit Ethernet ports. The folks at Macworld Lab put the Mac Pro’s expandability to the test, connecting 36 drives with a combined 100.63 TB of storage capacity, as well as a number of other devices.

Type an em-dash on an iPhone
Typography and punctuation geeks rejoice! It's easy to type an em-dash on the iPhone's or iPod touch's virtual keyboard. To do so, tap the .?123 key to switch to the numeric keypad. Then touch and hold on the Hyphen key to reveal a pop-up strip showing an em-dash. Slide to the em-dash and release your finger.
Note that this basic trick works with many other keys on the virtual keyboard.
