I have the kindle keyboard, a nook tablet, and a ipad. I like the kindle for reading outside and when I don't have wifi, it has free 3G. The iPad is nice for reading at night, I don't have to keep a light on to read. I don't use the nook anymore because as a tablet it doesn't compare to the iPad but if all I was going to do with it was read it's ok. I guess it depends on where you want to read and what else you want to use your reader for.
