So many choices...perhaps you can tell us what you have been using this past year and "where the shoe pinches" - where you have noted limitations in what you want to do.

For instance, screen size might be very important, if you have vision issues.

Do you need a specific operating system? PC or MAC or Linux?

Replacement warranty - how long? - warranty against defects? - warranty against breakage?

External keyboard? mouse? large screen?

HDMI? DisplayPort?

Storage? Large HDD or smaller faster SSD?

Thinking these through will give you a happier result.

 

Most importantly what is your mother's budget?
