There's no denying that the GC, at this point, is no longer competitive on a serious level with the PS2 and the Xbox in the U.S. as far as sales -- and, to a certain extent, the sheer number of upcoming and released software -- go. That much is true.
But the implication the writer makes is that not only is the GC not competitive in these fields, it is not worth getting as a videogame machine. That is completely ignorant, and I think that's what most people in this thread are having trouble with.
If you cannot see the value in any of the three current consoles -- especially with how cheap hardware and software is this late in the game -- you're a closed-minded buffoon. Period. The author's recommendation should have recognized this fact, stating that the GC, although clearly not as supported as its competitors, does have some gems in its library, and is certainly worth a look, especially with its low price point.
