I'm technically in biotech, but it involves significant software development. Pretty much everyone uses a Mac/iPhone, although the software (for running molecular simulations) itself is run on Linux clusters.
This is my experience, but I rarely meet an Android user who doesn't openly express that they wish they had an iPhone. There are a few moralists and uber hackers that I meet that are contrarians, but they are few and far between.
Out of curiosity, what field are you in?
At my company in SF doing heavy systems work, we're 80% Android
