"Caught Dead"
I'll tell you what, we met about 3 dozen photographers at a convention before our wedding, and interviewed about 10 of them. One thing was simple a fact a that time, when we asked one about their equipment (cameras and computers alike), if they used a PC, whether or not they had Photoshop on it, they were immediately crossed off our list. It wasn't that cut and dry, it wasn't like the fact they didn't have a Mac got them disqualified, no. When we discovered they had a PC, we asked how they managed and edited their photos, what kind of cameras they were using, and how they integrated photos and videos into their work if they were also a videographer. Every single one that had a PC was far less professional, they pretty much just "took and cropped photos" instead of "managing and editing" photos. They also tended to have inferior equipment, only one or 2 cameras, some were even using PnS cameras as their "backup" cameras...
I've head several friends get married in the lest 5 years, and been to a lot of family weddings as well. ONE had a non-Mac owning photographer. Apple may only have 9% of the market, but they have about 75% of the photographers, and for good reason. Lightroom is a nice app, but it's just not as good at project management as Aperture. It may do a bit aperture doesn't, but any real photographer is going to use Photoshop or Gimp for more than simple cropping, editing, and basic effects. That's not Aperture's role.
Adding the ability to make projects portable, and sync them back to a larger collection later is impressive. This really should have been highlighted in the article. That's a tool real pros can really use...
If you're a pro photographer, and you try out a Mac for 90 days, you will not go back to PCs for your professional work. The same applies to videographers in most cases. Some of the best wedding videos I've seen were done on a Mac with iMovie alone by people in the wedding party, vs. professional guys who charged thousands for professional videographer services, and handed over inferior quality garbage that took days to produce on a Windows box running a multi-thousand dollar video suite. We've done whole wedding videos, taking film from as many as 6 cameras, in a matter of hours that look better.
