In some ways I have to laugh at this...that Apple is hoping small business will "...adopt the company's Mac platform for their operations."
Keep on hoping, Apple.
So, like, what business platform software does a Mac run? No, I'm not talking about MS Office or Firefox. Real-world apps for finance departments, sales, marketing, customer relationship management apps, etc...I'm sure businesses with only 10 people can run some $89 software package to pay their bills, but "small businesses" are not just 10-person companies...some are 50+ persons.
It's one thing to buy business computers to surf the web, send some emails, and run MS Office...it's another to actually connect all your employees to true business applications. Not to mention that a business is now going to have to find an IT person who will support 100% Macs?...email, networking, hardware, end user desktop support, end user hardware support, security, etc? I'm sure someone will reply here that "there is no support needed because Apple is just so awesome!"

But hey, maybe it's time to start up an IT outsourcing gig that specializes in only Macs.
Also, depending on what the small business NEEDS the computer to do, they may certainly not plunk down 3x more money for a Mac than for a PC (for example if they only need their employees to answer email and do web-based stuff...any personal computer on the planet can do that). Small businesses tend not to have money to blow on expensive alternatives.

My uncle, on one hand, has owned his own business for over 30 years...small 5 man shop...1 computer...a Mac...that only he touches. Always has been a Mac, always will.
Apple has been out of the business sector, in reality, for decades...I really do not see them ever getting back in other than an extremely small marketshare percentage (Apple's general personal computer marketshare has been below 10% for like 20+ years...Apple's current business marketshare must be at like 0.4% or lower).
