Yes I have their handy little screen capture tool AshampooSnap3 on my win7 netbook. Not quite as good as SnagIt on my main system but then it is free
I use Snipping Tool which comes built-in with windows 7
<snip>
I have never used it, but I rather doubt it has the functionality of AshampooSnap3, which has image editing and a slew of other functions than you can shake a stick at.
One that I particularly like is the image capture and a save output directly to email, video capture, capture scrolling window (text & Web site) and the annotations are very varied, etc..
