Mum really wants a tablet, but it has to have office on it, a detachable keyboard with trackpad and play flash based Facebook games 
Which pretty much means win8 and as much as I love win8 I find it hard to recommend a tablet due to there specs, price and lack of models.
Don't worry she uses win8 and likes it, so that's not an issue.
Does the atom handle flash games ok and any other slow downs?
Budgets only £400 which limits the options.
