I disagree with the article on three grounds.
1) Some "Enterprise" features are popular and useful in a domestic context.
2) Whilst Macs are a long way from being the tool of choice for big business, they have long supported small business, and their are a number of small businesses out there loyally using Macs, who would be abandoned if Apple were to drop support for business.
3) In order to be taken seriously Macs need to be seen to be functional in a business environment, many domestic customers would not buy a computer unless it had some of this functionality, even if they didn't really need it.
