Remember! You can't go back to iOS 6!
In an attempt to head off the usual outraged posts, please remember thay once you install iOS 7 you CANNOT go back to iOS 6 no matter what some techie tells you. If you plan to update your iPad to iOS 7 make sure you and your apps are ready for it. Make sure you understand the changes that iOS 7 brings to the table. This is no maintenance update. This is a major re-engineering with major changes in the look and feel. Some of your apps may need updating. Some devlopers may not be ready, most will.
Remember the bottom line! Once you go to iOS 7 you cannot downgrade to iOS 6 if you don't like it or if you have issues with some of your apps. You will not be able to take your iPad to the Apple store and ask them to downgrade you to iOS 6.
