My son is 6 at the moment, soon to be 7. Whilst he is happy prodding at mobiles and tablets for simple games, youtube etc, he's itching to go at the PCs in the house. Also at school, they are starting to talk about making little powerpoint type documents and research of animals and what not. Is there are good way of introducing him to desktop / laptops ? I don't really want to let him loose on my PC login, so is there are good way/setup of doing it. Its almost like I want a kids version of windows. Super simple, but enough to do simple tasks. I dont have a mac, but could setup a linux machine rather than windows. Any ideas ?
