So I've had an iPad 2 for 3 years and finally recently sold it. It's impressive for an iOS product that had 3 years of pretty good software support (iOS 5-7). I also had the iPhone 3GS & 4, with iPhone 3GS supported iOS 3-6 pretty darn good, while iPhone 4 only got good iOS 4-6 support (oh iOS 7 on iPhone 4...). Do you guys think iPhone 5s (and current generation iPads) with A7 chip will be another durable product that can support at least 4 generations of future iOS? If yes, then it must be a pretty good investment, just like 3GS and iPad 2.
