She has already been languishing in Wales...
Hey. Back off Wales, it's lovely
That said I agree with Zonk. we can't say for sure what she has or has not done as a private citizen. Maybe she has been working hard, privately, maybe she's been lazing about exactly as some media like to say & she's been enjoying her free time, no-one can say absolutely. I'm personally willing to give her a chance & see what she does when she actually is a member of the Royal Fmaily not before & certainly not when she was "just" a potential wife for William (ok she seemed very likely but never absolutely certain til the engagement is done & dusted & the marriage done).
I say wait til after the wedding & then judge her on what she does or does not do as by that time she'll have to actually account for what she does & the tax-paying public would have a right to know what she does. Everything previous to that time I'm perfectly fine with regardless of what she did or did not do, I don't know what happened & I never will know, plus really it doesn't change anything anyway so what does it matter. I give her some credit for having lasted so long with all that scrutiny on her & not snapping at the press at all (or anyone around her).
