"it is nearly imsbpsiole to run a totally secure web presence, especially when you are the size of Sony"  This argument is fairly sound, no system is 100% secure or will ever be 100% secure. You can disconnect a computer from any/all networks and keep it in a safe only to find that someone steals the safe. However you can make it as difficult as possible for hackers to penetrate your defences. ESPECIALLY! when your the size of Sony. Sony has the finances to employ and contract the best security personnel available, buy the best equipment and hire the best in developing a secure methodology.Such a large organisation has a duty to protect that data and do more than they have done so far. In the case of the first breach they should have re-evaluated all aspects of their security. Not to mention their poor response and timing to responding to the breach and warning/reassuring their customers. "Nearly Impossible" shouldn't be an excuse...
