I have been exploring different methods of storing non work related docs, files and information in the cloud for easy access.  I want to access from multiple locations and from a variety of devices.  The best solution so far is google aps, toodledo and drop box.   The new iphone app for Drop Box is great.  For task management, I am trying Toodledo which is not fully baked but has a very usable iphone app.  I have been more successful with it than google tasks or Outlook tasks.
