iPhone 6 Plus VS iPad mini

Hi guys,

I'm the happy owner of an iPhone 5 and an iPad Mini.

With my iPad I use to read books and watch movies; I often use Quick office in order to edit and create Word files.

I'm trying to figure out if I can be confortable doing the same things with an iPhone 6 Plus.

Is the 5.5" screen enough for reading books, handle quick office documents and watch movies?

I'm looking forward to hearing your opinions.

A great day to you all.

Thanks in advance.

Ross
