Over the last few years, I've become more of an Apple nut and started to appreciate buying the latest and greatest from Cupertino. However, doing that led me to buy the iPad 3 and upgrade to iOS 7 on their respective release days. For the iPad, it looks like that purchase was a bit fool-hearty since the iPad 3 was replaced with the iPad 4 in less that a year, and with better hardware specs that can support functionality like AirDrop - something the iPad 3 can't do. As for iOS 7, while I think it is fine, there are a few regrets I have from upgrading the day of release. In the future, I think I will wait a bit longer before upgrading. All of this has me thinking about my desire for an iPad mini. I love my iPad 3, and until iOS 7, the tablet operated really well. For reading over long intervals, the form factor and weight of the iPad mini is better, except for the screen which is killer on my iPad 3. So if the iPad mini 2 comes with a Retina, I want to buy it, but my experience says that I should wait a generation to avoid a repeat of my iPad 3 purchase. What do you think? Will the mini 2 require enough engineering novelty that might make it a riskier purchase than waiting for the mini 3?
