I want to buy a laptop for my children for study purpose. I want to teach them about app, ppt and animations painting etc. And this could not be done with tabs or pods. I want to connect internet with LLN. Please suggest me which laptop will be best for them. I'm worried about speed. As children will do use hardly and roughly. So it should be working like computers.I'm thinking about Dell or apple. If it will be good?Thank you for cooperation.
