Get her a Barbie one and she will probably throw a tantrum.
Even young kids at that age learn to use computers at school and will probably know how to use a computer for games Etc.
It is when they get a bit older and want to use Messenger programs that the problems normally start.
Probably a lot of her friends will probably have one or maybe getting one for Xmas.
They are never to young to learn and it will probably also help with her schoolwork.
As long as you are there to watch over her and make sure she does not spend to much time on it I think it would be Ok.
Remember laptops are better used on hard surfaces like a table.
Some use them when lying in bed which can be dangerous as they overheat and can go on fire.
Anyhow best of luck it is your decision on whether you think she is to young or not.
If you go for one just type Pink laptop into the search bar and it will come up with the company's that make them.
