I'm doing some research to help my friend purchase an iPhone 8 (will be her first iPhone). I'm not all that savvy with cell phones, so my main questions are: 1 - What are the advantages of having both a Mac computer and an iPhone (as opposed to a Mac computer and an Android phone) ? i.e. what kinds of capabilities will be provided by the compatibility between the iPhone and a Mac computer (my friend bought a new Macbook Air) ? Will she be able to easily transfer/sync/back up contacts, photos, videos, etc between the iPhone and Macbook ? Once the iPhone and Macbook are paired, will she be able to type and send text messages from the Macbook ? What else will be easy to do between the iPhone and Macbook ? 2 - Is it true (I've heard) that most iOS apps on the Apple store cost money while Android generally offers more free apps ? Did you pay for most apps you got from the Apple store or get them for free ? I know that this depends on the individual app, but I'm asking you to generalize. 3 - How easy is it to transfer data between an Android (her old phone) and an iPhone ? Thanks !
