I keep a moleskine notebook with me all the time where i sketch and write my ideas on the spot. I use mindjet's mindmapping software to elaborate on those ideas and store the files in a brainstorming folder on my portable harddrive and laptop. A copy of that folder is also in Google Drive to have access to the files and documents whenever i need them. I frequently use evernote and flava and sync them both, especially when i take snapshots with my mobile.
