I don't feel like the interface is really that bad, certainly not as bad as the article makes it. The storage problem on Wii is a huge oversight on Nintendo's part, but has pretty much been discussed to death already. We know its a stupid and easy to solve problem, and according to Iwata, Nintendo is finally getting around to fixing it. Beyond that, the other problems listed don't really bother me. Having grown up playing the original Super Mario Bros., watching the Mario sprite run across the screen collecting coins and breaking blocks is both nostalgic and fun. And the coins don't represent progress, the blocks do, rendering that entire part of the argument useless.
Also, most of the Wiiware and VC downloads are very small, especially when compared to some of the stuff you can download on 360 or PS3, meaning very small download times, at least on a decent connection. By the time I got into a real game on Wii, most any download would be finished, defeating the point of playing a game while downloading. It makes much more sense on the other consoles who offer much larger downloadable content, and thus much longer download times.
Finally, the credit card form isn't really that cumbersome to fill out, and not saving the information does keep a parent's credit card number out of little Billy's hand. While this security doesn't matter to an older gamer like myself or the writer, it is very important for younger players, to which the Wii is appealing, ones who would be tempted to run their parent's credit cards to the limit on Wii points.

1. I laugh at the people who thumbed those posts down. Obviosly a Microsoft/Sony fanboy who had nothing better to do.

2. Everything with Wiiware is simple, it was designed so that the entire family can do it. The interface is simple, downloading is simple, the only difficult thing is storage.

After reading this a almost agree.

But WiiWare looks really fun. I hope that they come out with better games
