So my parents are windows users and I want to get them an ipad for x-mas. They have wi-fi and would just be getting them the ipad without the G3. My questions are: 1. Is the ipad fast over a wi-fi connection? My parents seem to have fairly good wi-fi, will streaming videos be ok? 2. the windows issue..... How would set up be? I have a mac so could configure anything that's needed, however i live many states away so would need to do this once, give them the ipad and they'd be on their own. Would there be any issue with configuring to their wi-fi? 3. (note that i don't have wi-fi at the moment, so am very much in the dark on this) thanks for any input!
