This gets easier!
I have cellphone with 3.9GB internal and a 119GB SIM for extra memory. If you have Word you can make a .pdf with any content you want. I aggregate info on Moss, or ID keys for Dawn Redwood, AHS Registered Hosta Names, my B-B-Q baste, or anything of specific nature that I might want to consult when I'm laying drunk in somebody's yard and I want to impress the squirrels with my command of all knowledge and ID what kind of acorn or Pine cone I'm laying on. I save the file in Word as a .doc file (because I can't edit a .pdf file if I want to add more data or photos later) and then save it again as a .pdf file. I can store the .pdf in my SIM memory and call it up anywhere,
on the face of the Earth! If you have an IPhone you're out of luck. Herewith, reduced to a .pdf, a sample handout that may be of interest to people who are interested in collecting Moss for use in gardens or on bonsai, but don't really want a degree in bryophytology:
