From Wikipedia, the free encyclopedia Evernote is a suite of software and services designed for notetaking and archiving. A "note" can be a piece of formatted text, a full webpage or webpage excerpt, a photograph, a voice memo, or a handwritten "ink" note. Notes can also have file attachments.
VocabGrabber is word cloud resource that allow you to enter text and then it automatically generates a thesaurus of word meanings. Looks interesting for helping students with difficult vocabulary.
iPad/iPhone--App for recording student behavior. Free verson allows you to follow 5 students on 3 behaviors.
Pro-version is customizable and probably worth the money--good reviews on Teacher's Assistant Pro.
I might try the free version first and then upgrade.
