One of the benefits to having an Android phone is that you can customize and change almost everything about it. You can even change the way your apps and widgets are presented to you by changing what's called the "launcher." The launcher is a lot like Explorer on Windows or the Finder on the Mac. It's the program that allows you to see files and applications so you can run them. The iOS launcher is called SpringBoard, and Apple doesn't let you use any other launcher. On Android, however, you can download third party launchers that change the way your home screen operates.
Michele is having issues with her iPad 2. The Wi-Fi is dropping out and her apps disappear and reappear. Is it wearing out? Leo says that what Michele is dealing with is a "Springboard crash." It may be corrupted. She should try to backup her iPad, which she should do regularly using iTunes. Once she's got it backed up, she should do a complete factory reset. It may even need to have a DFU reset.
