I got an iPad for the family the other day and after using it for a while, it got me thinking: are there any plans to add user accounts to the OS (or as it is a mutiple device OS, than just to the iPad?)? That way, I could sign into the device and have my email configured, sites saved, etc. and then my wife could sign in and have her email configured, etc. Maybe have differing setups for the apps on each page.
