I'm thinking about getting one of these tomorrow (or at least try) but before I do, there are a few things I want to understand first. 1. How does the ipad manage documents. For example, if I'm using pages or something on the the ipad and save a document.. where does it save to if I want to open it later to work on? Then, more importantly, can I quickly transfer documents through bluetooth to and from my computer? or do you have to use itunes for tranfering everything? I've never owned an iphone, ipod touch and rarely use itunes so I have more learning to do than others. My last two questions are.. can you print from the ipad? and will there be external keyboards for landscape mode? thank you!
