"Under $500"? I only tried a few, but they all seem to be well over $500. E.g. The HP 5102 they list at $415. Well it is $774 even from their own link. It is on sale, but that sale takes it down to $660, not really that near $415. Similar story with the Acer. Maybe some of the others were more accurately listed, but I decided the article wasn't properly written and stopped bothering.
