Couldn't agree more.
I love my Kindle for reading long-form (novels, non-fiction). But I read a lot of medical journals and while you can read them on the Kindle, it is sub-optimal at best. Plus I'm a pathologist and most of my journals have pretty pictures where color is nice to have. I'm currently using a rooted Nookcolor (which is okay), but I'm a recent Mac convert, so I'm looking to pick up an ipad on the refresh.
