Some quick impressions.
The Wii is different -- too different for those who like gaming the way it was last generation but not different enough for those who wanted a completely immersive experience. Thus, both groups tend to criticize the console. Those whose Wiis sit in closets or boot sales them tend to fit in these categories, but most likely in the former.
Is the Wii perfect? No. But neither is any console. (PS3 ends Sony's BC promise, Home is late .... Xbox 360 has too extra purchases, DRM on XBLA .... PSP can be hacked too easily, lacks second analog stick ... DS requires trade-offs (GBA BC for multimedia) has graphical limits ....).
But anything with a 47% marketshare and 34M units sold (not the 30M stated in the article -- which was reached in mid-July) is not a failure.
Again, it is not perfect. It is not everyone's ideal type. But it has reached a new audience. And with its attach rate about the same as other consoles, it is doing fine. (This group is extreme, most people buy less than 10 games for their console -- and yes, I know that attach rate measure mean not median, but generally means are higher than medians, particularly where there is a lower bound (zero) but no effective upper bound).
