The fire is a half cooked version of android. You can buy the fire, it has good hardware spec. Then goto XDA and root and load a full version of android and run any android app you like. very nice. Even the cheap pro scan tablets are a better alternative to the tied down expensive yuppie apple hardware. I went that route for about 6 months, I drank the apple flavored kool aid and bought everything, mini with 27" cinema monitor, MacBook pro, iPhone, ipad etc. Played with it for about 2 months, it sat for 4 months and I took a huge loss. So much for apples great resale value. I am back with an all windows ecosystem for 1/4 of the price, better performance, cheaper programs that run just as good if not better and as far as im concerned easier to use as well.
That said, I am running an android tablet for my navigation in my jeep as I had it sitting around and its a dedicated unit for my jeep now. It works fantastic and it was inexpensive. WIN WIN. No extra hardware to buy to make it into a full GPS unlike apple, free apps available to do the work if needed and no pretentious apple logo.
