A picture is worth a thousand words.
Dropbox, by way of contrast, is worth several hundred thousand words, backed up nigh-instantly to every machine you use, with version information and restore capability that goes back to the creation of the document.
I probably already sent you an invite to this, but if I didn’t, let me know, and I will.
I’m using the free version as an easy transfer point between my two laptops (vs. email), but I know it’s very popular among cartoonists for transfer/sharing of graphics between different platforms and locations. Interesting about the versioning available.
I have it installed on my laptop and my main writing computer. It allows me to take notes at school (Mini-Lappy) and write at home (Desktop PC) while keeping all my notes and projects current. Bonus: If the wife wants me to edit something or I need her to print something while I am at school, she can work on the PC logged in as me and we can move files back and forth via Dropbox. Nice indeed.
