I am not so much of a techno whiz. So, the deepest I have gone in e-notes is an App on my phone called (Keep my Notes). It allows usage off-line and allows Adding several pages. So, I have a page for garden To Do list, a page for Family To Do list ..etc. and one page for Reference numbers like medical file number etc.
I have no use for online stuff and do not feel the need. After retirement I am at home most of the time. Some people use smart phones for EVERYTHING from paying at the store ..etc. I feel sad for them because you should not rely that much on one gadget. If it fails you are in BIG problem
These days I am having a tech problem with my phone and shows how much helpless we are without them. So IMHO we shoudnt squeeze our fate too much within this one gadget.
My soapbox. Sorry.
