Not the battery, but the thing itself. I've found threads about battery lifespan, but I'm wondering how long to expect to keep the device. I have an IPad2 but I didn't want to post in that specific forum because I thought it would be interesting to hear about other versions as well. I've had my device just over three years and have updated to IOS 8 - 8.3 I think was the most recent. It's still mostly doing fine, and I probably don't push the limits - I use it mostly for e-mail and web browsing, plus streaming videos. But it has started blacking out on occasion, i.e. when I have tried to delete an e-mail with an attachment (far from every time). No problem bringing it back but it is annoying. I don't know if maybe I shouldn't have expected the device to tolerate iOS 8 (but then they shouldn't have offered it, should they? hmmmm), or if it really is just getting old. How long have you folks found these things to last?
