Crippled Android
My biggest complaint about the Kindle Fire line is it's Android...under the hood. But you can't get under the hood without jail breaking the device. Android is so limited on these devices they shouldn't be allowed to call it Android. It should be called Kindroid. Android is entirely crippled on the Fire. If you are accustomed to a standard Android OS you will be disappointed with the functionality of the Fire version of Android.
Sounds like a challenge to me.
