Like a favorite old t-shirt you've worn since high school, some tools are impossible to leave behind. Tell us about the one you can't imagine doing without.
We all have one: That app or tool we just can't live without. The one that follows us from upgrade to upgrade and from new computer to new computer. For some, it used to be something like WordPerfect. But for others, it's something more basic, such as a favorite screen capture tool or text editor.
Whatever it is, it's time to share it with the world! Tell us what your favorite tool is and why you can't live without it. In a week or so, I'll follow up with a look at some of your selections. You can share your comments in the discussion below or email them directly to me.
