Not multiple choice?
Between the three of us we have 2 iphones, an ipad, an iPod, an android tablet, a kindle, a laptop, and a web-enabled flatscreen TV (gets hulu, netflix, etc on it's own).
The iPhones and can sling wifi to all of the other devices.
Most commonly we use the Apple adapter cord to connect our phones, ipods or ipads to the TV watch movies. I try to remember to rent a movie or two on itunes before we leave and have it already downloaded to the iPod so there is no need to use streaming data while we're there, but inevitably, we end up surfing.
Why do we bother leaving the house? Good question.... lol.
