I did not buy ipad1 and now I think I want to have an ipad2. I went to apple stores these last couple of days but they don't have the one I am looking for. I am wondering if I should buy the 16gb or the 32gb. I am interested in wifi only. I also know that I may be upgrading to ipad 3 when it comes out, so then would it be easier to get a good value out of the 32 or the 16gb mobel. What has been your experience when you upgraded from 1 to 2. I also want to know if I can play movies which are stored on my external hard drive connected to my macbook and watch movies inside the house and also when I am outside with wi-fi connected. Also, I am looking for a way to hook it up in my rav4 for the back seat passengers. whats the most economical and easiest way to do it.
