It's likely only the "best selling desktop computer ever" because of the abundance of choice for non-mac users. Not sure how that's relevant to the parent's point though...
Exactly because the iMac is Apple’s main desktop offering for consumers, they need to know who the buyers are. I have no doubt they know exactly what their target market is and they’ve described it over and over:
– People who want an easy to use computer
– People who want a relatively hassle-free experience (good built-in apps, little chance of malware, good support from the manufacturer)
– People who value build quality and aesthetics and who are willing to pay for that
