You need less to come out to the market the new portable console from Nintendo, Nintendo DS (announced for 2004 in the USA and Japan). The latest news say that the new console, which includes Wi-Fi (802. 11b), will allow its users to make calls over the Internet (voice-over-IP) from any Wifi hotspot. Still do not know if you can use any of the existing VoIP services (such as Skype) or if it will only work with a proprietary system from Nintendo (for example, to communicate while you are playing online), but it seems an interesting novelty.
On the other hand, and in view of the recent departure of the Nintendo DS, have already dropped the price of the Gameboy SP in the USA and Japan, $99 to $79. We assume that soon lower prices will also reach Spain.
