Amazon just opened the floodgates to its forked-Android powered Kindles (7-inch only so far).

The original with some beefed up internals is just $159.  The new HD version (which closely matches up with the Google Nexus 7) is $199 for 16GB and $249 for 32GB.

(Or you could wait a month and probably not hate yourself :P)
