I think this article touches on something important. The psychological barriers that must be crossed as part of switching from one thing to an alternative. We frequently test by bringing users into a lab and as part of on-site trainings for our products where we ask people to use our product on one of our test platforms such as a tablet or laptop with additional tracking enabled such as eye and hand movement. It is not uncommon for these users to be unable to create a test account as without their home computer or phone they cannot read and respond to email confirmation requests. Of course this might be highlighting a shortcoming of our registration protocol but that aside, this barrier is real (at least for some of our users). If users can't switch browsers because their "account information" is tied up in them, switching to a new OS is going to be completely beyond their ability.
