Heck, I'm all for newer products but it sure seems some aren't really happy/satisifed with what they currently have. I guess it depends what you own now but heck some folks still like their ipad 1 and ipad 2 so ....
yeah my doctor was viewing my medical records on an iPad 1. i asked "ever thought of upgrading to the newer iPads?" he said "why? this works great" when i think about it, it makes sense. he doesn't use it for games, just for medical records and looking up meds etc. the guy probably makes 3x what i make as an engineer and he's using an older iPad. just shows that even if one can afford it, doesn't mean he will always upgrade.
while yes, Apple did not extend iOS 6 to the iPad 1, it's still an incredibly capable device. i'm still running iOS 5.1.1 on my iPad 3 for some jailbreak apps that aren't compatible with iOS 6 yet. so i'm running an OS that's 2 years old and the only issue i ran into was that i can't upgrade to the newest TED app which requires iOS 6.
this is why i choose Apple for mobile devices - their long term support is superior to that of Android
