I have no idea, I have an iPad through my work, which I sue for work and Netflix. I get them free apps, which they enjoy, like big cat Collins books, drawing ones, puzzle craft, number things, some hideous barbie and lego ones, y'know the drill, and they take photos with it etc. My inlaws like to spend £100 each on their gdcs, of which I have provided two, and as the kids get idler and increasingly spoiled it is harder to think of things they want, particularly as birthdays are weeks away from Xmas and get another £100. Fwiw I buy them a birthday party each, and this year got three Furbies for £100 from Argos, one each for mine for my niece who will be there for Xmas too. They get toys year round from our stupidly good charity shops (yes my fault I know).
Anyway, sorry totally off topic. Is it worth letting them get her one? Or will she still just want my iPad because it is faster/better pictures etc etc. my ds is older and they gave him a 3ds last year so he is getting games for it.
