I like Amazon and love my Kindle BUT I can't say I'm impressed with their durability. I'm on Kindle number 3 in as many years. I got their original reader, which I think last about 1-1/2 years before the screen went. I've had a Fire for 2 years and the screen is pulling away from the "frame"; there's about a 1/8" gap all the way around, and the AC-power plug is temperamental. It still works, amazingly enough, but I don't travel with it anymore. I didn't abuse either one though the original Kindle reader did go backpacking with me. I don't think there's any excuse for the Fire to have fallen apart.
My husband and son still have their original iPad's, going on 4-5 years. They take them everywhere and are handled much rougher than I do my Kindles. I've replaced my Kindle reader with the cheapest one they sell simply because it's the lightest option and, for the price, I won't be broken-hearted if it fails in a year. But I won't be putting my money into the more expensive Kindle models anymore. As much as I didn't want to, I'm moving to the iPad mini.
