I'm kinda sad that even though tablets are multipurpose and go for less than $200, people still manufacture paper notebooks and books. What happened to save the environment, reuse, save the trees?
I scan to share and to tag and as insurance for complete loss of the 'daily book' I carry round.
In practice...
Everything I have on paper I did not lost, even when it got damaged for whatever reason (like a flooding...)
But I already lost lots of electronic data (specially with some bad flukes, like dropping a backup HD on the ground, and then figuring the original broke down too for some reason)
And lots of electronics.
Also finally, using paper to write in the bus or metro here in Brazil does not make people point guns at your head, while using electronics does. (I am not kidding, I got robbed at gunpoint a couple times)
