I use iTunes as my primary media collection, between iTunes Radio, Movies and TV I buy or rent, and even drop in videos from other sources so that I can AirPlay to my AppleTV. I don't sync my iPhone, but I use Automatic Downloading for music and videos, which is very convenient. This works because I can listen to those songs or watch those movies on my Mac or my iOS devices, so it's worthwhile to have it in my library. That is not the case with iOS apps, which take up space on my SSD and offer no functionality. So yeah, I usually resort to texting myself links to Apps to avoid downloading them from iTunes.
