As was noticed a long time ago on roughlydrafted.com (before it became a pure fanboi site without anything interesting to say), it's exactly the same in the PC market. Apple grabs something like 80% of the market in PC over 1000$, hence they grab almost all of the hardware margin; then Microsoft grabs most of what remains, and all PC makers are fighting over breadcrumbs.
Yes, but they're much happier making budget hardware, handing over the majority of their profit to Microsoft and fighting tooth and nail over bread crumbs than they would be otherwise. Gotta pursue your dream dont'cha know. It's a freedom thing. Also, even if they make a loss, they will make it back in volume. (since that appears to be their actual business strategy, whether to place sarcasm tags around the preceeding sentence is left as an exercise for the reader)
Small nitpick: roughlydrafted was _always_ a pure fanboi site with little or nothing of interest to say.
