The reason why I don't like these sort of things in game consoles is because then people will be watching what Nintendo will do about it. They probably know that M$ will try to outdo Sony with their cash sword, but Nintendo only wants to do games, and if people are demanding Nintendo to focus on something other than that well, Nintendo could lose business simply for not complying. And we see that already with the DVD playback on PS2 and XBox.
SO in other words, Sony and M$ are 'forcing', in the slightest sense of the word, that this is the direction consoles take: Gaming platforms that also act as multimedia devices, and can fit into your everyday, multimedia electronic 'needs'.
People will start saying "Why doesn't Nintendo have this in their console?". When the next-gen consoles are with us, Nintendo will still be the only platform that only plays games, and even we, the Nintendo fanboys, will start saying "Why doesn't Nintendo put this into their next console just to keep up with Sony and M$?"
And while Nintendo is constantly pressured into making their next console with other features, I don't think they should. Nor should any company be pressured into remaking/redesigning their console simply to satisfy the multimedia market.
