I think you'd be surprised as to how much it would change the way you look at your trips. having a tablet is extremely handy. I have mem map on my phone also but its a bit to small. Being able to plot, measure distance, set waypoints and make notes is very handy indeed. All the paper hema maps are available from the app, or there's mud map or ozi, but that can be complicated, or androzic for ozi.
Im heading to simmo desert in August and all the paper maps are available on my tablet and its been very handy to plan ahead.
