His article starts out with a description of how most computers are manufactured and marketed.  He states:

"Computers are made and marketed as all-purpose machines, but for a lot of people they have a rather limited job description: Web browsing, e-mail, MP3s, digital photos, the occasional letter . . ."

He then goes on to describe how computers are used and how software installations can be a task that some do not wish to undertake.  He goes on to make the point that if you want a computer with the essential software already installed, one should get a Mac.  Pegoraro states:

"Instead, find out how the computer will be used once it's plugged in. If the user isn't interested in installing new software but would rather use the tools that come with it, you should shop for a Mac"

"That's not the cheapest option, though. A Mac Mini, iMac desktop or MacBook laptop -- starting at $599, $999 and $1,099, respectively -- will often cost more than a PC with about the same storage and processing power. But it is the easiest option."

The article then shifts to a discussion of how a Mac is easier to setup, how Mac OS X has a stellar security record, and how the included software on a Mac is better than the titles found on a PC.

"An Apple machine will be much simpler to set up and maintain, thanks in large part to Mac OS X's outstanding record of security. It will also include Web, e-mail, photo and music software far superior to the junk on most PCs."

Then a few comments about Apple's Boot Camp software are mentioned that describe how the new Intel Macs can run Windows:

"A Mac can read and write almost all PC files, including Microsoft Office documents. Apple's switch to Intel chips even lets a Mac impersonate a PC, running Windows with the help of such software as Apple's free Boot Camp"

Switch To A Mac Commentary
Prior to the Intel switch, Macs were criticized for only running a fraction of the software found on Windows.  Over the past few years more and more software titles have become available on Mac OS X.  Furthermore, a growing number of developers are developing software for Mac OS X.

Thanks to Boot Camp and virtualization software such as Parallels, a Mac can run the largest selection of software.  Only a Mac can run Mac OS X, Linux, and Windows.
