Don't know what you intend "artificial" to mean.
Every maker targets products for certain customers.
The current iMac is not targeted towards power users. It is more closely aligned in the spirit of the original iMac.
Same with the Mac Mini, or the MBA. The base Mini is aimed for someone who wants a simple computer to plug into some need. The MBA is aimed for someone who needs a basic laptop.
Apple offers multiple products for people who need more computing resources than base offerings of the iMac or MBA or Mac Mini offer. If you need more, buy more.
