Sounds ok...but it's SOFTWARE that runs a business...not the hardware.
Small businesses (define "small"...under 10? under 50? under 100?) certainly need basics like MS Office type software, basic accounting software, email, and other stuff depending on their business.
But as the small business grows to 50 or 100 folks, Quickbooks ain't gonna cut it...ditto for Sales software and other needs depending on your business.
Macs are nice...but at the end of the day it's the software that powers your business. If the software isn't available on Mac (or a good choice), you won't be buying Macs. It's also well known that for personal computing tasks (web surfing, email, MS Office, photos, music, etc) it doesn't matter if you use a PC or Mac so why spend more? Let's also admit that buying Mac hardware is much more expensive than buying PC hardware...usually about 2x as much. Please don't reply with the "but not if you competitively price them!" garbage. There are plenty of reasons why Macs are in 1% of businesses...and price is definitely near the top of that list. I'm not hating, I'm just stating. And what about that support contract as your small business grows?...there are far fewer Mac technicians out there than PC folks (queue the "but Macs never break!" comments) if you want to shop around for Mac support at the business level.
For the small business under 10 that never intends to grow larger (for numerous reasons), sure, buy Macs or whatever you want. But if you plan to grow above 50, there are a lot of things to consider when choosing a Mac vs. PC.
But hardware generate wealth for a nation.
