Using iOS Device With Braille Display To Replace Dedicated Braille NoteTaker

Braille on Apple Products
Hi Everyone, I very recently purchased a Brailliant BI 40 to use along with my iPod Touch 4th Generation as a replacement for using a dedicated Braille NoteTaker such as the Braille Sense or BrailleNote Apex. For those of you who have done this, how do you manage access to and storage of files and folders, and what have you found to be the most convenient way to transfer material between devices? I have considered Dropbox, and also have considered using Pages on both devices. Is either of these choices more preferable than the other? Or do you have any other suggestions? Thanks in advance for any light you can shed on this topic! Desi
