I am considering buying an Ipad. I am debating as to whether or not I should wait for the 2nd generation ipad or make a move now. I have read where one of the complaints with Ipads is that they do not have a USB port. I have very little experience with the ipad. What does not having a USB port limit me to not being able to do with the ipad? Is this an important missing feature of the ipad? What can I do through itunes or other ways that will accomplish what having a USB port will do? Thanks for any advice.
