I've had the Kindle app itself crash a time or two, but it never caused the mini or my other iThingies to crash. Safari crashed my iPhone 5 last Sunday and it took a while to get it to reset. But no crashes like that on the mini yet. I'm still thinking that nearly 500 apps, many of which will run in the background or at least wake up and phone home periodically, is more than any tablet should have. To each their own of course, but I cannot imagine even being able to run 500 apps one time each per month! Just not enough time in my schedule. Do the math. If one ran each of 500 apps for 5 minutes once a month, then one would need to be on their iPad for nearly 41 hours and 40 minutes. In my case there would be a lot of lonely, neglected apps sitting around forever wishing someone would run them.
