Okay, I've gone through the list more thoroughly this time (my kids are asleep), and these are my conclusions.
1) Given the huge number of artifacts, especially common artifact creatures, you could build a very nice mono-color deck without sacrificing card quality.
2) Given the prevalence of Myrs and Talismans, two cycles of artifacts that give cross-color mana, you could possibly (depending on what you get) build a very stable mana base for a three color deck. I'm not saying that it's likely, just that we should keep our eyes open for the possibility.
3) Given 1 and 2 together, they kind of cancel each other out in most situations.
4) The two colors with the most immediately obvious artifact interaction, at least at the common level, are white and black. I expect that a lot of people will play these types of decks simply because they are so obvious.
5) On second glance, red has better artifact destruction than green does (in this set, at least), and it also benefits more from having artifacts in play. Green will receive obvious benefits from your equipment, of course, but it can't do things with artifacts the way the other colors can.
6) Having not played the set (obviously) I predict that black is the weakest color, followed by green, followed by white, red, and blue in a clump--I can't pick which is better or worse at this point.
