Hmm, yes. When even Ed Bott* reacts in the following way.........
"That shouldn't be surprising. If you advertise "unlimited" cloud storage, perhaps you should expect that some people will take you at your word and move large collections to the storage space you so generously offered? Did no one consider the possibility that some customers with large digital media collections would find this offer insanely attractive? (The owners of "all you can eat" buffets could easily have told them what was in store.)"
.......... and uses such words as "renage" in his commentary one has to conclude that Redmond have not exactly covered themselves with glory on this one!
