At "under $100" budget, that is the way to go. Quite frankly, I would have one of those, save that I already have an iPad. That is a market that Apple is definitely not going for, and where they will probably succeed. I still remember my wife and I talking about it, and one of those might solve her needs for a "digital book reader" much better than the previous models.
Ditching the physical keyboard is also a +++ in my opinion. The product is finally mature enough.
