What are the alternatives to the OneNote 2007 feature for doing screen clippings to capture information ?
Evernote has a similar feature, and the nice thing about it over OneNote is that it syncs online and is cross-platform, so you can access your notes from any browser or rich clients on Mac and Windows. Even has an iPhone client.
PixClip is a free and lightweight alternative to OneNote's screen capture feature, and works much the same. Just like OneNote, you can assign a shortcut such as WinKey + S.
