As usual, Mac users gloat and PC users struggle. Now the field is more even if you use Firefox 4.x and an add-on called 'awesome screenshot.' Two features stand-out from my minimal use: Grab part of a screen easily; Annotate the capture; The author has a cloud service, but I could not figure out how to use the link for PC. Something other than putting the URL between <img> tags is required. You can save locally and upload to PC. Pretty damned nifty. If you use it more than infrequently please pay the author his requested $4. The hardest part for me was figuring out how to activate the add-on. Look for a button on the far right of your bar at the top of the window.
