In the car, I use my Pscan on a small Toshiba NB550D laptop, running Windows 10, these things have a 10.1 inch screen, they are @ 10 yrs old now and obsolete, so you should be able to pick one up for next to bugger all! Mine came from an opportunity shop or more commonly referred to as an opp shop here in Oz (what you’d call a charity shop in Pomgolia ) it cost me change as it needed the hard drive replaced, which I happened to have a suitable solid state drive laying around.
Just did a quick check on Oz flea bay, and found a couple of equivalent models from other brands for under Aus $50
I find it better in the car than my iPad, as it sits on the passenger seat with screen up, so as I can see it without having to hold it, it’s heavier than the iPad and as such doesn’t slide about as easily and if it goes flying and crash lands, it’s not much of a loss!
I have an 11inch Acer, as a spare waiting in the wings, ready to go.
Please note that I only watch it when the car is stationary or I’m in the passenger seat, with someone else doing the driving!
