Nothing beat a filesystem to organize stuff, it also happen to be great way to find stuff fast..

- Folders like \doc \tutorial \ideas \recipics - Store everything in .txt and .odt - Replicate to favorit cloud storage

- For comunication: Fastmail, Skype

- Contacts & calender: Fastmail

- Keep a diary in a mail folder, I send myself a mail every now and then with a subject to an alias, that gets sorted into a "diary" folder
