A:AnswerThe answer depends on what you want to do with it and what you consider to be a "computer". The iPad is fundamentally a computer, but functions a little different due to the nature of the device (it's a touch tablet) and the operating system (iPad OS vs e.g., windows). If you use a computer for large / complex spreadsheets, database management, coding, or creating documents with a lot of complex formatting, etc., or you like working in multiple windows at one (i.e., more than 2 or 3), then this is not for you. If you are a content creator (i.e., videos, blog, etc.), graphic artist, or just want something to read email, consume content (e.g., YouTube), read books, etc., then this is definitely an option.
A:AnswerWith an internet connection and an Apple ID, you can make and receive calls in the FaceTime app (first sign in with your Apple ID, or create an Apple ID, if you don’t have one).
