No, not 'nuff said, unless you are willing to accept a flawed argument. Specifically:
"The Nexus 7 (2013) is 7.87- x 4.49- x 0.34 and weighs 0.64 lbs. It now uses a 16:10 1920x1200 (2,304,000 pixel), 323ppi screen, and gets 9-hours of battery life - in airplane mode."
I am sure you are familiar with Anandtech. His reviews are... thorough. Here is the battery life. I would paste in the testing protocol, but let's just say it is ... well thought out. 12.23 hours vs 8.87 hours for the iPad mini.
38% more battery life with 37% less pixels. Can you connect it from there?
A retina mini using Nexus7 level hardware could exactly match the current iPad mini battery life.
I was all iOS (retina ipad, iPhone, apple tv) until a month ago. I have the new Nexus 7 and I now choose it 90% of the time over the retina iPad. And that is at home. Colour me surprised as I was putting at least 6 hours a day on my iPad. Of course the portability has me packing it off site often now as well.
Apple had better step up its game this fall. I use a icloud email address, I schedule everything on ical, most of my texts are imessages, all my contacts in Contact etc. I am all in with iOS and still I am seriously contemplating getting a Note 3 or a Nexus 5 when they are out.
The new Nexus 7 is that good.
I'll end with a line from the anandtech conclusion:
"The build quality is great, the display is amazing and the hardware is fast."
