Actually from what I've seen in the computer industry is that there are usually two logos one that features a wide arrange of colors and shading (even some gloss to make it shiney) and one that's a basic two-three tone image. That's not to say it's black and white. I rarely see black and white logos anymore (minus apple of course, but they're more white and a little more white... with some white thrown in for flavor). Take dell for example, they use blue and white to make their basic logo and that thing gets slapped everywhere, but for digital purposes they use very complex coloring.
Now I admit that most of these ideas wouldn't cut it because we need someone with better art skills to design it, but I'd also think that almost any of them could be the logo. Indeed I'd actually argue that a pure black and white design could not be a logo simply because b&w lacks the professionalism requirement of a modern technology company.
That said, I do think that whatever logo we do, we should make sure that it follows dell's example and works in such a way that you can slap it anywhere. I mean you see that D-funky E-L-L anywhere and bam, you know who it is. Even if it's just raised black letters on a black case, that image is unmistakable. I think the pi shadow one could meet that requirement. But I still also think that digitally speaking as a logo for the company to appear on the website and places like that (or print media for that matter) any of these logos (after being cleaned up by an artist of course
) would be excellent choices.
