I am assuming you are referring to off iPad storage... since the iPad has plenty of storage in its solid state hard drive. For off iPad back-up, I would use my access to my computer at home over the internet via 3G or WiFi, or to my MobileMe account storage. Simple.
I was hoping NOT to have to pay for 3G for the iPad. I already have so many accounts and my ATT bill is a killer. I would like to use WiFi but it is not private enough for sending my writing. Is there another way? Would Mobile Me also be sent in a way that is readable by others in the hot spot?
(Yes, I am a bit dumb -- sorry!)
