I could've sworn when I read this initially, it was $89! I had some stuff to do so kind of filed it away to look at later and now it is selling for $99.
Also, this article seems like an advertisement/blogspam, plus with the sudden price change - I'm very suspicious.
That said, it looks like a really neat product. My daughter has sleep issues (falling asleep - staying asleep) and we've tried all sorts of different lighting to help (she can't stand full darkness) and I'm wondering if a self dimming bedtime lamp like this might help her.
