I build TodoPaper and combine it with TaskPaper and DropBox to sync across my PCs and Macs and iPhone. It's a plaintext file format that also has a number of open source projects that highlight the files when you work in Vim, Notepad++, etc. Example of the format:

  Project:
  - task
  - task @done
    - sub task
