I'm not bothered by my iPAd2 screen compared to my iPhone4 screen either.
A Retina screen would be nice for the mini but I think what's holding me back is the processor. It's basically an iPad2. I'd want a bump in horsepower.
I won't a cellular model. If Apple drops the price far enough on the Gen1 when the Gen2 is released I may go that route. It really depends on what the Gen2 has to offer
Ah, I hadn't considered the processor. Because I'm still using my iPhone 4 and iPad 2, I have no idea how much faster the iPad 4 or iPhone 5 are by comparison (ignorance being bliss in this case).
If I am buying a new device, I suppose it doesn't make much sense to buy something running the same tech as my 2 year old device... Decisions, decisions...
