When I tried to send text messages from my desktop Mac, all of a sudden I was dropped into a horribly complex maze of things that make no sense. I can't even figure out how to send an SMS without someone sending me one first. I tried reading all of Google's docs, installed all the software they told me to install, and in the end I went back to the Nexus 4 to communicate with Jen. Later I realized I could do what I needed to with the Voice website. But there were problems there too. I ended up having to enter the number manually, my contacts list was useless in that context.
