I have been looking at different tablets. There are lots of options, but I keep coming back to the Ipad. My question is should I get the Ipad or the Ipad2? I don't think I will use the camera, so that isn't a big deal. Also, when there is an update to the software it is the same for both the ipad and ipad2 correct? So, is there much of a difference between the two and is the ipad2 much faster than the first version? Thanks.
