Managing notes and todos

Managing notes and todos: "We all write notes while working. There are plenty of software available to maintain your notes or todo lists. Some are fancy desktop decorators like sticky notes, calendars or todo-list in side bar. I’ve been looking for a solution that lets me manage my notes and todo-lists. Many of the items out there does either notes or todo-lists; not both. Ideally, I would prefer just writing notes and todo’s automatically extracted from it. I zeroed in on six main contenders – explained in the order I used them."
