The iPad, at first glance, looks like an enlarged version of an iPod Touch or iPhone. It’s 9.7 inches diagonally, compared to the iTouch’s 4.7 inch diagonal screen so it’s approximately 4 times the width and height but not thicker than the smaller devices.
Like the iTouch and iPhone, the iPad synchronizes with iTunes and is not really designed to be anybody’s primary computing device. Although it seems like you can do almost anything on this device, it’s not designed to be a primary or only computing device – Apple expects you’ll have a laptop or desktop computer as well.
The iPad runs the same operating system as the iPhone and iPod Touch, which means that all your existing applications should run on an iPad as soon as the devices are available – the existing apps will just look bigger on the iPad screen. And developers are already starting to develop iPad specific apps, which are designed for the larger screens and can take specific advantage of these.
Built in accessibility features
All existing iPhone accessibility features will be available on the iPad. This means VoiceOver, screen zoom, white-on-black display, mono audio, and closed-captioned content will all be supported on every iPad. It seems from the iPad specifications that fewer languages will be supported, at least initially, which will impact some VoiceOver users.
