Why didn't ipad bring its own weather!

Because there is no official pre-installed software, compared with iPhone, iPad lacks its own calculator, compass, clock, weather, stock market voice memo and other applications.

IPad is a series of tablet computers released by Apple in 20 10, which is positioned between Apple's smartphone iPhone and notebook computer products. (There are four virtual program fixed bars on the screen) Like the iPhone layout, it provides functions such as browsing websites, sending and receiving emails, reading e-books, playing audio or video, playing games, etc.
