Searching the map for your target given only incomplete information is much faster. It also scopes the map to your screen size, paper does not do this, you save time finding the right resolution.

It sounds like the real problem you are experiencing is that you stopped checking your route. If you treat it like a paper map on crack then it’s a great tool. And, to be fair, it does sound like you run into more frustrating ‘wtf!’ problems than others.
