I purchased an iPad mini (for the gf) and an iPad 4 for myself. But I'm still on the fence whether I want to spend the extra money on the 4 or should I just stick to a mini and call it a day. My question is: How does jailbreak affect the mini? Do any of you notice lag because of the 512mb of ram? Retina really doesn't seem like a deal beaker but it is nice. Looking forward to everyone's input.
