I was wondering the same, but liked the looks of the new nexus 7.2 so ordered it based on the fact that is has a GPS that does not need a cell provider. I carry an iPhone 4s/Verizon provider, and have an iPad 3 without. Of course, the iPad GPS will not work without a wireless connection or paid provider such as Verizon or AT&T. More dollars a month to use GPS programs.
Having used the 7 tablet for the last 3 days, I can tell you I love it. I bought the 32g model, and am rapidly adding the apps. into it's large memory!
It has quickly become my travel companion in the car and boat. Being older, 72, with less than perfect close up vision, I find the screen and keyboard much better for me.
I also think that the sound from the speaker on my nexus is better with it's case on, than my iPad 3 with the case off!
I am using Swift Key trial ver. 4.something, and it's a nice app. for changing your keyboard.
So, for me, I think it's a matter of "a bird in the hand." and not having to wait for the new, yet, unshipped iPad Mini!
Good luck!
