Well, well -- what's this? Amazon's Kindle DX just arrived a little earlier than we expected, looking every bit like the big brother to the Kindle 2 it did at launch. Seriously -- apart from new, less comfortable keyboard, externally you're just looking at a Kindle 2 with a bigger screen. Turn it on, though, and you immediately notice the orientation sensor, which is almost too sensitive. We're loading this thing up with content and putting it through its paces right now, but in the meantime hit up the gallery below for the unboxing and some comparison shots.
