I'm a guy who likes running their own software, writing their own software, making changes, etc. on my computer. I moved off of Windows back in the XP days because it became clear that I was going to lose more and more control over my OS. (Those forced Windows Updates drove me over the edge...)
However, I like having a phone that stays phone-like and is locked down. I'd like to be able to play FLAC files on my iPhone, but I can live without that. I can live with just using Safari as a browser. I consider my phone to be tertiary to my computing lifestyle, so if I want to do specific things on my phone, I just don't do it. It's worth it to me to not worry about that.
I hope this makes sense- honestly, until I read the summary, I hadn't thought much about how I care A LOT about what I can do with my computer and very little about what I can do on my phone!
