The Apple iPad was designed by a team led by British-born design executive Jonathan Ive (or translated as Jonathan Ive), and the sleek, ultra-thin product reflects Ive’s My admiration for the talented German designer Dieter Rams. The iPad is a series of tablet computers released by Apple in 2010. It is positioned between Apple's smartphone iPhone and laptop products. (There are 4 virtual program fixed bars on the screen) The same layout as the iPhone, providing browsing websites, Send and receive emails, watch e-books, play audio or video, play games and other functions.

Device features: diverse input methods, good mobile performance. Since the iPad tablet is no longer limited to the fixed input methods of keyboard and mouse, it can be operated by handwriting and touch, so whether it is standing or moving It can be operated in all. If it is a pure tablet, it can be made thinner and lighter, so it has better mobile performance. Full-screen touch, better human-computer interaction Using keyboard and mouse for input on the computer is actually a compromise of human-computer interaction. Imagine if we drag and drop the window with one finger, and use two fingers to zoom in or out of the photo. Isn’t it more in line with our actual behavioral habits? And all this can be achieved on the iPad tablet full touch screen. Reading in hand can be used as an e-book iPad tablet computer, especially a pure tablet computer. The relatively lightweight size and weight allow people to hold it directly in their hands for operation, which changes people's habit of reading on computers. Dual-screen tablets suitable for reading are already available. Handwriting recognition, convenient text input. The iPad can input text and draw pictures with a stylus like a handheld computer. It also supports digital ink technology: the text shapes input by the user's stylus do not need to be converted into text, just like we use an ordinary pen to write on paper. The words below are the same, which greatly improves work efficiency. Although it still has a thin and light body, the battery life is not inferior. Apple officially promotes that the iPad's battery life can reach 10 hours under normal web browsing conditions, but judging from the test of the Wi-Fi 16GB version, actual use can reach 11.5 to 12 hours. It's quite outstanding.
