£300 max budget, looking for laptop for shared use with 8 yr old who is keen to learn more about laptops/computers

[bunchamunchycrunchycarrots]

I'm a complete technophobe so haven't a clue what's what. I've a dodgy old netbook I use for net surfing mumsnetting so this will mainly be needed for educational purposes etc. I'd prefer it to be fast, good clear large screen, and easy to use (for me and DD).

Any recommendations?

Thanks for all the replies/ suggestions. I'm going through all to check them out and then hopefully ill be able to make a decision. Thanks.
