When the built-in SSD in his MacBook Air failed, Macworld’s Dan Moren decided to try replacing it himself (surprisingly, at the suggestion of an Apple Genius). The process was easier than he thought, taking only 20 minutes.

Copy Excel Selection as a Picture
Want to show someone a chunk of an Excel spreadsheet via email or iChat? You could take a screenshot, but if you want to show just a portion of the Excel window and you don't use a utility like Snapz Pro, you can do this right from within Excel 2008. Make a selection, hold down the Shift key, and choose Copy Picture from the Edit menu. You can select whether the selection will be rendered as though it was shown on screen or as though it was printed. Then just switch to your desired destination and paste.
