I like mine electronics rugged. So mine phone, camera and lights all are. So a rugged tablet would fit in that bill.

I'm not so sure about the e-ink screen shows enough detail on the maps, without color. Color definitely makes reading map much easier.

Also i like to peak at mine maps occasionally and then stuff in back in a jacket pocket. I don't think a tablet would be handy for that purpose.

And i wonder i just want to use the map on the screen and put mine compass on it. A real compass must be easier to sight. Not so sure if i can draw on the screen to create lines, like on a real map.
