Josh, Agreed. Not to mention that for most of us, the computing power of a 2-year old laptop is more than enough, especially, if you plan to use it with a limited set of applications. E.g. my weather station runs on an 8-year old laptop and is doing quite fine.

What I meant was that 12v power supplies are often available. 12v cigarette lighter adapters that put out 19v for laptops. Interestingly though, I did notice today on my laptop that the battery is putting out 12v. It takes 19v from the wall adapter but only 12v from the battery. I feel a jerry rig in the future.... And you're entirely right about the cheapness of a laptop that is a year or two old. I've been picking up these dell rigs (latitude d830) that come used from businesses for ~$100. I've had them for about a year and a half and today just realized that the bios date is 2013! They are really very new (newer when I got them) in the grand scheme of things, but old as far as technology goes. I can trash a ~$100 laptop every 5 to 10 years. We're so close to the point of diminishing returns in terms of what most of us do on a day to day basis.

But it is easy to check. Laptops have an extra advantage - they get obsoleted pretty quickly, so you can get a pretty decent used one for around $250. And you get all the internal power protection you need.

In fact that was one of my biggest concerns. The stability of a usb connector from a 12v boat supply just started feeling really unreliable. I overcame it with a UPS addon "HAT" for the PI. That is one nice thing about a laptop or even a tablet device. They don't shutdown just because of a sketchy power connection and they will auto shutdown if the battery gets too low. They're portable and have a considerable screen built right in. They are also natively designed for 12v power supplies. I guess that's why Rasberry PI fits my needs so well. It is a cheap device that I can afford to ADD permanently to the boat and sustain depreciation and obsolescence without flinching. The user interface can be ANY of my other personal devices and doesn't have to be permanently tied to the boat or regulatory transported to and from.
