DOS Emulator In and Out of App Store
gent01 writes "A company called Fast Intelligence got DOSBox running on iOS and dubbed it iDOS. It's been stuck in review for the app store for some time. Evidently the iDOS app was in the app store this morning, but it has already been taken down."
If I had DOS then I could have installed an old version of cygwin and then got my favourite GNU tools working! Jobs would have had a fit it I could have done that.
