The PPI is important to the reading aspect - sharper text makes for more pleasant reading, and the 9" form-factor is just a bit too big to be comfortable, in my books... especially when you can go up an inch and get the clarity of the new iPad. The Nexus 7 is nice and light, despite its drawbacks, and has a screen like a paperback's in size. The 9" is bigger than a paperback, yet smaller than a hardcover... and at the same price, I can get a 7" with an SD card slot, or an Acer Iconia A200 with a 10" screen, MicroSD slot, HDMI support, and a PPI not much lower than this offering, but with more capability.
Sure, you lose the rear camera... but what type of person uses their tablet's camera to take pictures all the time?
