I used to do similar, more with numbers and tax/price arranging, though you know those older versions of blackberry phones that you can type on like super quick? Like, Z10 or something, those come in handy for writing lots of stuff on cause I find I can type super fast like way faster than touch screen on them. You could just pick up a cheapo one of those then email the files to yourself. I kept my old one cause it's like a digital pocket wordpad pretty much.
