Appearance
Compared to most other tablets, Amazon placed the front camera to the left other than the top. This makes the 7 inch Kindle Fire HD wider than Nexus 7. 
Kindle Fire HD’s back surface uses similar design as iPad. This does a compelling job of making Kindle Fire HD feel thinner. On the bottom, we see HDMI & USB port and Mic. 3.5mm headset port, volume button and power button are placed on the side.
The corners of the tablet are more rounded than its predecessor, with a glossy bezel going around the display — a little bit of the rubberized backing creeps out on top of this. Two Dolby speaker are placed on two side. The back surface is easy to get fingerprint.
