For most applications, our iPad is fine (at the risk of reigniting the old arguments on this matter). But there have been times in the past 6 months where we took water over the bow that challenged the helmsman to stay standing and may well have pulled a removable mounted unit off. That is not necessarily the type of sailing that most people do (nor that we would plan for) generally.

Also, in addition to overlaying radar, getting real-time AIS has proven very useful. Not quite sure how to do those two things on our iPad.
