Apple has recently announced an extension on its repair program for certain MacBook models produced between May 2006 and December 2007. Qualifying machines display a flashing question mark on the screen when turned on and are eligible for a free hard drive replacement. Customers with symptomatic MacBooks should bring them to an Apple Authorized Service Provider or an Apple Store within 3 years from their original date of purchase or until August 15, 2010 (whichever is longer). Apple also said it will reimburse users who paid out-of-pocket to fix this now-covered issue.

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.

Apple Extends MacBook Repair Program
by Doug McLean 
What about those of us who have a Superdrive that stopped working? Apple knows it's a problem, & I don't want to pay $300 to get it fixed. Mine quit after some update.
This repair program is unrelated, but you should take your Mac with its ailing SuperDrive to an Apple Store or call Apple about it.
Thanks Adam. Maybe I'll call Apple. I did take it to the store and they said there was nothing they could do and wouldn't acknowledge there was a widespread problem with the drive. But a call is a good idea.
