They are not available until the November 15th. :(
I have ordered mine and am on the waiting list and should have it in my hands on November 17th. I have a kindle now and love it, but I really would like the color.
I have 3G and the Kindle Fire will not have it. This means I will need to be at a WiFi hotspot to access the web or order from Amazon. Just like now, all your data will be housed at Amazon. The present kindle has the E-Ink which isn't affected by glare. The fire will not have this. I do not know if you have a limited storage alotment. I will have to check into that. Other than the price, those are the negatives that I come up with now.
I've promised my brother my kindle with my kindle fire comes and I think I might have done this prematurely because I will not have anything to fall back on, if the kindle fire is a disapointment.
