Do you all know - what kind of cable would I need if I wanted to hook iPad up to a regular television to watch movies? Also - I'm confused about the charging adapter. It looks to me like what the iPad ships with is just the capability to charge via USB with your computer. Is that right? If I want to be able to charge from an electrical outlet I need to buy an additional adapter? I'm presuming it can't be used with the wall charger for an iPhone or MacBook.
