i've pre-order during the batch 4 period and delivery has been pushed to late october.

i don't understand the concern with security or someone being afraid that the device will cease to function in case the company goes belly up. if you are concerned about security, then don't turn on wifi and transfer files direct from a computer to the device using the usb cable.

if you are worried about a stolen device with sensitive information on it, then those sensitive pdfs should be password protected before you transfer them to the device.
i don't yet have my device to test with, so i transferred a password protected pdf to my kindle. and on opening the file on the kindle, it does ask to enter the password. after entering the correct password, the file opened up. i'm thinking that the reMarkable would work the same way with password protected pdfs.

however, to password protect a pdf, you need the paid version of a pdf reader. both adobe acrobat and foxit phantom are paid versions of acrobat reader and foxit reader, respectively. and both allows adding passwords to pdf files.

on the other point, if the company does go belly up, you should still be able to use it in offline mode until the device itself dies for whatever reason. but it won't die because there is no connection to a server.
