I've purchased a Mod Notebook and am waiting for it to be delivered. They launched first, so I get to compare you to them naturally.
Mod Notebook Pros:
-Notebook and scanning included ($25)
-Only less $10 than Moleskine and includes digitization, syncing
-Prepaid shipping envelope
-Native Mod App to read notes
-Syncs with Dropbox, OneNote, Evernote
Mod Notebook Cons:
-Shipping delays in the current order, still waiting after a month from unexpected high demand on their part
-$5 more expensive than you guys
Papersync Pros:
-Cheaper ($20)
-Can use any notebook
Papersync Cons:
-Mailing cost not included
-$5 less but no notebook
-No dedicated app
-No apparent syncing
On first impression I would splurge the extra $5 for Mod Notebooks every time. I would definitely consider you guys for old notebooks I have already used up - but I would expect the cost to be closer to $15 for future notebooks to save against Mod. Good luck!
