PS will definitely not work. As far as I know, pps has not launched an IOS-based platform (but you can watch videos through other video websites), so these two functions cannot be realized by the three products you mentioned, and other functions can be realized. Ipad is actually a big touch (ipod touch), and iphone is also an enhanced version of touch (you can insert a mobile phone card to send text messages). All three products can browse the web.

In addition, IPOD is a broad concept. There are many IPOD products, including touch, nano and shuffle, among which NANO and SHUFFLE are only simple music players mp3, while TOUCH has a built-in wireless network card, which can search for wireless network access.

If you want to achieve everything you say through Apple products, I recommend you to buy a MAC, which is an Apple computer. MAC is different from PC and has its own unique OS system, which is obviously different from WINDOWS. Both PS and pps have OS versions (for mac), which can realize the functions you need. MAC products include ordinary computer Macs and notebook MACBOOK, including pro and air. The former is an ordinary notebook, and the latter is an ultra-thin notebook (the thinnest in history), with no difference in functions.

IPAD is not a netbook, but a tablet is a product between a mobile phone and a netbook. If you need a netbook, don't buy an IPAD. If you want to use a tablet, you'd better use an IPAD.

IPHONE can surf the Internet in two ways. The first way is through the traffic on the mobile phone card, just like ordinary mobile phones. The second way is WIFI. In the environment with wireless network, you can search for wireless signals to surf the Internet without spending traffic.
