Encrypt iPad backup:
Your personal data on the iPad is encrypted—
scrambled so that if the iPad is lost or stolen, its contents can't be
read. The backup stored on your computer's hard disk, however, is not
encrypted. To make it inaccessible to prying eyes, activate this option.
A dialog appears asking you to define a password and verify it. See
Chapter 11 for more information about iPad security.

Configure Universal Access:
Click this button to enable options that
make the iPad more usable for people with impaired vision or hearing.
These controls mirror those found in Settings > General >Accessibility.
What if you want to connect the iPad to your computer but don't
want to sync? You can't change the automatic sync preference without
the iPad connected. Instead, press and hold Command-Option (Mac) or Shift-
Control (Windows) when you connect the iPad, and hold them until the iPad
appears in the sidebar. It won't sync.
When Apple releases updates to the iOS, which powers the iPad, iTunes
informs you with an alert. You can also click the Check for Update button
on the Summary screen to query manually. If an update is available,
you're given the option of downloading and installing it.
If you say yes to the update, you get to choose between downloading
and installing it right away, or just downloading the software for later.
The second option is good if you want to take advantage of a robust Internet
connection (for example, you're at the office or in a coffee shop with your
laptop) but plan to update the iPad at another time (when you get home).
iTunes backs up the contents of the device before applying the update, so
your data is safe. The process can take a while, so make sure you have a
block of time available (say, at least 30 minutes to be safe) before apply-
ing the update. The iPad needs to restart during the process.
