Yep.  Amazon's "official" Kindle covers roughly double the carry weight 
of the devices.  That's why I got a third party sleeve for my DX. 
Remember convenience?  The sleeve protects the Kindle when it is in my 
pack, and stays in my pack when I'm using the device.  This is why Apple 
redesigned the "official" cover for the iPad 2 as a folding flap that 
functions as screen protector and stand base.  It's all about 
convenience with these devices.

This is a big part of why I believe that resonant inductance will 
replace batteries.  RI short circuits the battery weight problem by 
eliminating or reducing the need for battery power.  An RI-powered The 
New iPad wouldn't need 42 Watt-hours of battery packs.  A 5 Watt-hour 
battery pack would provide enough power for about 30 minutes of roaming 
use or several hours of standby power and it would considerably reduce 
the total mass.
