The European Nintendo DS handhelds can get a $50 web browser from opera, leaving the US the only major market still without the device. Like most DS addons, this one utilizes the game boy advance cartridge slot and the DS's Wi-Fi capabilities. While it's a fairly high price for the product, internet functionality on such a nice compact device, $50 is a relatively small price to pay. One can expect the device to eventually make its way to the US, however details are vague at this point in time.
