I really hope the iPad Mini 2 delivers a Retina screen and a cheaper price point. And I hope it doesn't compromise battery life or size/weight to achieve the Retina display.
If they can pull this off, I'd be very interested in it.
I'm not convinced Android is the same experience on a tablet. I want to believe it is, but it doesn't seem like it's so. It's not hard to believe.
It's the same thing with iOS between the iPhone and the iPad. iOS' shortcomings are far more acceptable on a tablet experience (except for the abysmal keyboard). For example, the ridiculous notification banners that drop down in iOS are far more annoying on a 4" iPhone, where it blocks a portion of the screen you're on and/or the navigational pane (I still think this is absurd design). But this isn't as big of a problem on an iPad because well, it's not really blocking very much; the screen is larger. It doesn't impede on what I'm doing or what game I'm playing nor does it block any navigational panels.
That's just one example.
I hope the iPad Mini 2 delivers. I'll be keeping a close eye on both this year's Mini 2 and Nexus 7. I may be willing to give Android tablet experience a try depending on how it plays out, or I may be willing to stay with iOS for my tablet (currently own an iPad 3 but want something smaller/lighter).
