Reference documentation on your iPad Homescreen.
Quite handy for developers with iPads. Point Safari to http://developer.apple.com/iphone/library/iPad/index.html#home for iPhone or http://developer.apple.com/mac/library/iPad/index.html#home for Mac Reference Library. Touch the + button in the toolbar and select ‘Add to Home Screen’. Now you always have your Reference Library available, unfortunately only when you’r online though. I wish there was an offline app version of this…
