There are also cheap dry-erase square maps that you can use markers on that have a grid on them which goes very well for 5e's positioning mechanics and such. You can draw the rooms on it and erase them (if no one is mapping in game) or leave the whole thing on it if they are. Some of them get to pretty good size. I like the 36" square ones. The best part is they roll up and if semi-decent quality will still lay flat when spread out without the corners being a hassle. If the corners are a hassle, this is why gaming books are heavy
Honestly, I am TT purist, I don't think 'technology' helps the TT experience much for the most part in that respect. It can do wonders for simulating a TT environment (ala roll20) but that is still not Table Top.
