I use screenshot tools all the time no matter what computer I'm on. One interesting Windows screenshot tool that I came across recently is called Greenshot. It's not the most feature-packed utility that you can find, but I'd say it ranks pretty highly seeing that it does come with its own image editor.

I've been using a Mac for nearly two years, and with as many screenshots as I take there was just never an app that quite matched the capabilities of SnagIt on Windows. I'll admit that Skitch was pretty close, but the screenshot editor lacked in a lot of different areas. My biggest pet peeve is the inability to manage/manipulate multiple screenshots on the same canvas... a.k.a.
