It seems like ages since Amazon introduced us to the $199 Fire at a hectic New York City event, but in truth that was only about six weeks ago. Maybe our perception of time is warped because we've been hearing talk about this 7-inch Android tablet for months now. Maybe it's because Amazon launching a tablet seemed like such a natural thing to do after Barnes & Noble paved the way with its Nook Color. Or, maybe it's just because the gadget Amazon shipped looks nigh-identical to the 7-inch BlackBerry PlayBook that we've had for, well, ages.
