Perhaps electronic guides won't replace paper ones but if I had to choose my customer base right now, I'd choose the one's using GPS, MacBooks, and iPhones and leave the sextant-carrying group to the paper guidebook publishers.

I know a lot of sailors that still carry (and use) a sextant. They invariably use it to back up their GPS. They also have many flavors of guidebooks, both electronic and paper and I think that's the point-redundancy, a very good reason to continue to buy paper cruising guides.

BTW, the OP has titled this topic "There's no reason to buy another guidebook" but then later posts:

but the reality is that there are few people like us with paper charts

.....now I'm confused...is redundancy good or bad?????
