Like Ian said somewhere else [paraphrased] "Nintendo doing the Nintendo thing in a Nintendo way"
I know. The second I read "Nintendo-like way" I was thinking "uh oh!"

I'll admit that when it comes to this video stuff I'm completely out-of-touch and not at all the target demo. The iPod Video comes out and I just question the point of watching video on this tiny little screen on a device that can't possibly have enough storage to hold a video of any decent length. To me it just seems like a novelty and if you wanted to watch video on the go a portable DVD player would work better. But people eat that stuff up.
With the Wii what is the point? I'm connected to a TV which likely has a DVD player hooked up to it. There are tons of stores that sell or rent DVDs. With minimal effort I have access to all sorts of great films and TV shows. I don't need to be limited by the selection on Nintendo's service and have no need for novelty videos when YouTube provides me with that legally for free. And my Wii is connected to a TV itself so I can just, you know, watch TV. If I just need a quick cure for boredom I can flip through the channels. Or maybe, you know, play one of the Wii games I own.
With the DSi it's the same "what's the point?" stuff I have with the iPod Video. It just isn't going to be a good enough for me to spend money on these videos regardless of what they actually are. And like the iPod the DSi has a primary function that already provides entertainment on the go. If I'm bored I can listen to music on the iPod or I can play games on the DSi. What do I need videos for? I might as well save my "video purchasing" dollars for when I'm at home with my TV where the sound and picture will be vastly superior.
I just don't get it. I don't get the appeal. I can't say for sure if this video stuff is a risky move for Nintendo or not because the whole concept seems worthless to me. The world is tethered to their portable electronics and I'm the outsider wearing a wristwatch and using the cellphone that came free with my plan.
