Not really a fan of Moleskine's notebooks, but this is interesting. But, Evernote's Page Camera feature that was added to the iOS app does seem to work just fine with other paper (I tested Field Notes w/ graph paper). It's just 'optimized' for the paper in these notebooks, whatever that means.
If it does make a significant usability difference, that would be pretty cool and I'd love to get some insight into why dotted lines would be simpler for image processing software to work with than straight lines, but... For now, I'm gonna keep on trying to bury myself with post-it notes...
