i saw in Flickr that you tour a lot in organised civilisation, for that we sure don't need a smart phone, paper maps are fine. when you leave into deep country side in the ex communist east EU countries no paper map helps you.
for example Romania, has aprox 30.000km unpaved roads, the villas you pass there all day long have nothing, no shops, no hotels, zero .... no food... having a smart phone there is very helpful from time to time.
