The "headless iMac" is the "Mac Mini." (Close-follower branding from Apple? Or synergy from their cooperative projects with BMW -- er, I mean, Cooper? But I digress, as usual...) Of course, they'll sell millions of the buggers. That's what they do: Create cute things that people want to buy, regardless of what it is or really does. But I swear, I'm different: I swear, I actually care what it does.
But is it an earth shattering device? Even without wireless, as it is, it could be, but in and of itself -- no. Everyone I know who's ever thought of getting a Mac wants one -- hell, I want one -- and yet, I don't think it will take over the low-end market the way it could if the price point were, say, $100 lower, or the base RAM were 256KB bigger.
But in another way, it will be revolutionary. Consider the size of the thing: It will now no longer be acceptable for PCs to be as big as they have traditionally been. Ultra-small variations on the ATX form factor, which are common now only among hobbyists and "gear fetishists", will become standard PC form factors, and will at the same time cease to command a premium price. They will drive devices the same size as (or smaller than) a Mac Mini, and aren't inherently much more expensive to manufacture than the larger boards; since Intel and AMD chips clock higher, they'll be faster; and they'll become radically cheaper as demand soars from people who've seen the Mac Mini, but still can't afford the extrapolated $800-$1000 price tag for a really capable, obsolescence-resistent MiniMac.
It's interesting to see where the rumors went wrong. The "iHome" branding turned out to be a red herring; it would be interesting to find out where it came from, because it so effectively skewed the speculative field in the days just before the presentation that it seems as though no one even tried to get spy shots of a Mac Mini. It's a lot smaller than the hoaxed pictures. The hoaxter dubbed it 'iHome', and various rumour millers reported with confidence that it would be "branded" as an iMac; neither turned out to be true. It was said to include WiFi in its base configuration; WiFi ("Airport Extreme") is an add-on, as is Bluetooth. Performance numbers were more or less right, though the rumors missed the fact that there'd be two base processor speeds. And to illustrate just how far off the original rumor was, the "headless iMac" was said to "share the 1.5" [1U, or "one rack unit"] height of the latest Apple G5 server; it's actually 2" tall. A picky detail, but it demonstrates how completely off-mark we all were.
It's tempting to speculate (as I'm sure someone has) that Apple planted rumors to throw people off the scent. But I don't think they need to. For what other PC brand would people bother to create physical hoax models? Whatever the explanation, the community of Mac users has a hardened core of Macintosh and Apple fetishists. In fact, I think they don't really try, for the most part, to get real rumors; they just make stuff up, because it's more satisfying than the truth. Anyway, true wisdom, to the Mac zealot, is received wisdom: It issues forth every January from the Dark Steve, from a well-lit stage at the MacWorld keynote address...
