I think folks are trying to push another false dichotomy, in that either there is advanced innovative new tech in a thing, or it's not worth any more money and spending on it is only a "lifestyle choice."
It's just not so. Putting a set of incremental improvements in a product makes it better.
Better ergonomics, including the balance and lower weight, makes it better (and for people whose health and comfort benefit, I can see this being far more worth spending money on than some geeky new screen technology) and better design is...well...better.
And, while of course there will be a profit premium applied, as Amazon is a for-profit company, good designers, engineers, market research, all of which is need to successfully implement even just incremental refinements, do cost money.
A lot of people here are stating their own (usually tragically uninformed) opinions about what constitutes better ergonomics or worthwhile feature improvements, as if they have not only tested them out, but as if they are the supreme arbiters of such things.

The price of this Oasis is too high for me, even if the improvements in ergonomics and lighting (which do appeal to me) are everything they claim. But I will likely be spending considerably more money than this on a new TV in the next year, because that's where I choose to put my disposable income. For people who put that same sort of value on an optimal ereader, there is nothing odd or surprising or foolish about getting this one to see if the improvements serve them. They are not "falling" for anything or "merely making a lifestyle purchase."

So, in closing: suck it, haters.
