Gaskin initiates his article by stating that he's not a Mac user but a casual user.  He sums of the first paragraph by outlining three primary reasons why people and small business are switching to Macs:

"But I'm hearing from more and more small business people who switched, and I've identified three primary reasons for the surge in Mac deployments: lower costs, Intel chips, and Web applications."

Gaskin moves on to discuss how Macs have become more affordable and makes mention of the entry level system, the Mac mini.

"Macintosh prices haven't dropped to PC levels, but they are closer than ever before. The Mac Mini for $599 costs more than an entry level PC desktop, but at least the Mac has an entry level, which wasn't always the case."

He goes on to discuss Intel-based Macs, Boot Camp, and Parallels Desktop for Mac.  Gaskin then moves to a discussion of how Web application growth is resulting in a rise in Mac usage.  I don't necessarily agree with his views.  My stance is that Macs running OS X lead to a better user experience thanks to Apple's end-to-end model.

Macs cost less?
In his final paragraph Gaskin puts forward the notion that Macs may cost less,  highlights how Windows Vista has similarities to Mac OS X, and how Apple's soon to be released Mac OS X Leopard operating system will keep Apple ahead of Microsoft.  He states:

"If you're going to buy new hardware to support a new operating system, you may find that switching to a Macintosh costs less and gives you more than upgrading to Windows Vista. Besides, regardless of Vista's new glass-like interface and Mac-inspired Gadgets, Apple still does Macintosh better than Microsoft copies Macintosh. And Apple is about to roll out its operating system upgrade to answer Vista, which should keep Macintosh that much farther ahead."
