The new thinner, lighter design language of the iPad mini. Hopefully the new screen tech and LED, along with incrementally improved battery tech, will make that possible.
Happy with the iPad 4.
I tried the Mini side by side and I rather take the size vs loss of resolution of display plus I need that extra space work things I am working on...
True, there are +/- to all tablets. But the OS is what brings it together.... Displays are getting better, but on a smaller end not yet... I have tons of iPad 2 in-service and they work just fine.
I'm still content with my iPad 2 and have no intentions of upgrading unless it craps out on me or something.
Speaker on the front!!!
