[Stylist] Methods for writing

[Vejas Vasiliauskas]

Hi, 
I hope you are all doing well. I have a question for this listserv in general. 
I've written pretty much all my stories on my Braillenote, starting with the classic Braillenote BT when I was 8, and now the Apex. I like how the braillenote's word processor responds easily to quick typing. As an added bonus, the documents are in KWB (keyword Braille) format, and are only readable to most people if I save them in a more standard format such as Microsoft Word, so I have always appreciated the privacy this has given me. 
I will probably soon be "graduating" to the Braille Sense Polaris. The word processor on it seems pretty good, but I wanted to ask you all which devices you use to write, and also which applications you find work best. I have tried Pages on the iPhone, which is decent but not always as quick as I would like. 
As an added question, how do you ensure your writing is private before you feel ready to give others access? 
Thank you so much, 
Vejas
