What's holding me back is I'm probably about to buy a 4.7" android phone...so 7" tablet is not really that much bigger - though I do recognize that 7" is probably about double the screen real estate of 4.7".
Also the resolution and screen are not that great compared to the HTC One X or Samsung Galaxy S3 I'm hopefully about to buy...further limiting the gain I'd get from having one of these. When would I pick up my Kindle Fire to use as opposed to my new phone's brilliant 4.7" 720p screen?
BTW I wouldn't buy a Kindle Fire for eBooks. I have a Kindle 3 that I think is great and don't need to replace (not to mention e-Ink > backlight for reading).
