I won't dispute that they're far more relevant today, but I disagree that they were borderline irrelevant circa 2005. They were quite successful selling Macs and had a credible alternative to the Windows monopoly.
The iOS stuff certainly moved them to a whole new plane of success, but I don't have to like it.
As a power user I don't 'like' it either. But I don't 'hate' it. I just use third party services when Apple's offerings don't fit.
The only bit I took issue with, is holding up Apple as having 'failed' simply because their focus is on other types of users. Particularly when they're serving those users at least as well as any alternative. And when those users are far, far more numerous than users like myself and their needs far, far easier to meet in an engineering and support sense.
