It's nice to see the price having a positive effect on sales. If people are buying it at this price before the big games are released, it shouldn't have any trouble selling when they are. Hopefully, the US numbers will be pushed over a million after this.
And yeah, the Kindle screen is amazing. It doesn't even look like a screen, it looks like a page from a book, and has no light so it's easy on the eyes. If they can make a screen like this for a game system, that would be astonishing, but I don't know if it will be possible to have it in colour or have it refresh fast enough to display 60 frames every second.
