Yes, as it happens, I spent around 1.5 hours last night looking around for a good mapping tablet, as YOA (Yukon Orienteering Association) is potentially going to get one to try and help develop local mapping talent up here.
That is precisely the model that I figured was the best bang for the buck right now, and if my tablet died today, that is the model I would go buy. The battery size of only 4200 mAh is a little concerning long term, but otherwise it looks like a good device.
The 6000 mAh one that I have (5 years old admittedly) is still able to just barely get a 7 hour mapping day in, if it is not in full sunlight all the time and I can drop the brightness to a couple of notches below maximum. It is kinda funny, but the tablet I have from 2015 was about that price point, with only (generally) slightly worse specs. Here is a comparaison of the two devices: https://www.gsmarena.com/compare.php3?idPhone1=712...
Frankly, the tech hasn't gotten
any cheaper in the last 5 years, other than that the camera has gotten better.
