Yeah i wondered the same, well a gen. would be great if you were home when it happened but if you are not i guess we are all out of luck. The only problem with the battery backups for a computer will not last long at all since i know that my one rack with back heat would kill one of those in less than 20 minutes. My only relief is that i dont have really bad weather and its very unlikely that the power would be out for to long where i live.
