Bingo. The only instance where I prefer phone calls over text-based communication methods is when I just want to talk about nothing with family members who live far away and who I haven't talked to in a long time, just so I could hear their voice. For anything functional, I prefer text-based methods all the way for a multitude of reasons. Having full logs of the conversation to reference later on is a huge boon when it comes to avoiding misunderstandings and getting things done.
