The best news from Apple's developer conference, which is taking place in San Francisco, is the iCloud. The demos at the opening of the conference have shown some important aspects of iCloud. You take a picture on one of your devices, which sends it to Apple's server, which pushes it onto your other devices. That's great. Another important advantage of the iCloud is that you have storage you can trust, which of course is well backed up.
However the greatest advantage is that the iCloud sets the iPad free! You will no longer need to have a Mac or PC in order to own an iPad. The USB-cord that held the iPad will be irrelevant starting with iOS 5.
Now iPad is for everyone!
