Personally, I think the could get away with just making it thinner and faster. What else would a tablet user want?
Lightning to USB 3.0 instead of 2.0.
if you handle a mini you'd agree
Outside of lighter (which it really needs to be, if you handle a mini you'd agree), thinner for some but not others.
USB 3 support is a MUST. Pic/file transfers are so slow right now, it's mind boggling why Apple updated the connector but went with 2.0 instead of 3.0 as the standard.
a. better file management. Ability to move files from one app to another without going through itunes.
b. Open With option for standalone files
c. Bridge the gap between phone & computer, by getting the tablet to have a unique experience & more features, not available on the phone. The iOS for the iPad should be tilted towards more content creation too. The problem is that Apple & most people believe that the iPad is a content consumption device, while in reality it should be a 60-40 split (content creation and content consumption)
e. Less dependence on the computer (itunes) and more standalone device
f. a more useful notification bar
Retina and better processor.
An upgrade over the current Mini without raising the price too much would make me happy and a buyer.
Yes yes yes. I really want Apple to set up a centralized document storage system that you can work out of and save into. This feature alone would be a great improvement. Right now, I kind of use Dropbox for that, but it's clunky and doesn't work well.
What sort of features would this be? You basically said you want "more features that are just for a tablet", but didn't really enumerate what those would be. And, yes, the iPad is primarily a consumption device. I think it's the nature of the beast right now.
You don't need to ever connect an iPad to a computer if you don't want to right now. I basically never connect mine unless I need to transfer some files or something. What exactly would you change?
