What the hell does that mean?
Mass... weight... do you really know the difference between both?
Illusion of being lighter because the keyboard, what's that? fyi, Oz, pounds, gr, all those are units of weight, not mass. And the Kindle, when probably a bit heavier (for only 1 oz) than the Sony 650, it is a light device, there is no doubt about it.

Actually, the right word is not plastic, but polymer. Plastic is a kind of polymer.
And yes, is used in industry in order to save weight on most electronic devices, including Kindle. Aluminum and other alloys are also being used, but increases the manufacturing price a lot, without providing a considerable added protection. This last statement is not true in the car's industry, but still you see a lot of modern cars using more and more polymers as replacement to some type of alloys, even inside the engine.
It sounds a bit biased coming from me (I own a Kindle) but it is sturdy and strong. Check by yourself in Mobileread; there are not many serious manufacturing problems with the Kindle, which is not true for other devices. Of course, like any other mass production ereader, you will find some of them with defects or problems, but it is not a rule and there is no relationship at all with its polymer based construction.
I like Sony ereaders but in terms of quality and construction, Kindle and Sony are hand to hand. The Kindle is also much more affordable and very competitive for the features that it provides, including access to Amazon's online bookstore which is unique and exclusive to the Kindle only.
