She does not care if it is Linux based. No offense meant. The PC runs so much faster that she is really amazed.
She is not one trying to download all kinds of stuff/apps into her PC which does mess up many Windows users.
It was easy to transfer her files and Favorites to Firefox.
She uses email, maybe opens photos from family and sometimes a You Tube video. She is very aware of Spam attemps.
Pay bills on line and she learned sometime ago, don't stay logged into any site any longer than you have to. I do the same. I never log into any forum until ready to say something and then I bail out.
Her email is web based and easy to use. Bookmarks are just like her Favorites in XP were.
I will send a donation in on this as I do not hear anymore complaining about a slow PC.
Put this in perspective we are both over 70.
I started with a PDP8 in 1972. Windows 3.1 in 1996. Left W98SE, a very good OS, but dated, in 2003.
