However, the Amazon Kindle Fire HD tablets, which were announced earlier this month, may be a bit tougher to crack. Or at least that is what some members of the aforementioned forum are lead to believe, based on evidence like the tablet's signed bootloader and the TI processor's security features. And when you think about it, it is in Amazon's advantage to be selling a locked down device. After all, the company wants to make money by keeping people loyal to its ecosystem, not by selling them expensive hardware. That is why Amazon Kindle tablets are so affordable, yet don't give you access to the so-called complete Google experience.
