Thank you for your article. I know this is an old post but, I am new to the Mac OS world and I am spoiled in XP with SnagIt from TechSmith (No, I don't work for them :)
i have reviewed all the option in your post and I think I have a good grasp of what they can do.
Is there anything in the Mac world that comes close to the screen capture and edit can do in SnagIt?
If you want to see a quick feature list, you can that here... www.snagit.com
This is a legitimate inquiry, if you know of a Mac tool like SnagIt, I will purchase it today.
