I am very psyched about getting an iPad. It definitely fills in a gap for me with my unique work circumstances. I spend at least half of my year outside the U.S., working in foreign countries for usually about 2 months at a stretch. Therefore, I have never seen the benefit in having an iPhone that is locked into a plan that I would rarely use. (However, I can't live without my iPod Touch). So, I am definitely interested in the 3G iPad with it's no-contract pricing (although I've lived this long without it and don't NEED it), but before I leap, I do have some questions and/or concerns. As I've never used 3G or Bluetooth before, this Newbie needs help with the following technical questions to solidify my my purchase choice. 1) Is the 3G radio a major battery drain on the device? If so, is it possible to turn this off when not in use. 2) If available in a foreign country, would the iPad let me connect to the foreign 3G carrier for two months, come home use AT&T for a month, go abroad again and use the same or perhaps a different 3G carrier. (AT&T roaming rates abroad seem outrageous) 3) Using Apple's Bluetooth keyboard would suit my needs better than the keyboard dock. I am a director and must take notes (in a studio and/or in a theater) on a 3 hour show and then about an hour (maybe more) of walking around giving notes - and do that twice in one day. With the stated 10 hour battery life this seems doable, but is using the Bluetooth keyboard for such an extended period going to substantially drain the battery? Excuse my ignorance, but that's why I need some help. Thanks!
