I want an application that has:
A rich text editor built in.
A main menu with an intuitive interface for easy navigation.
It should be able to record my class periods' times.
Have a calender built-in with an agenda/to-do list
Automatically sync between my devices in terms of calender events, homework, files. (iPhone, iPad, Win 7 PC)
Be able to mark a page as homework or assignment directly from the document or *.pdf.
