Before considering any recommendation, keep in mind, it all comes down to preference.
The obvious cons of Macs is that they are more expensive and less compatible with SEO programs. Pros include that they are visually appealing, less prone to viruses, and they have a simplified GUI.
That being said I run my VPS on my Mac as well as a dualboot setup for backup. I have NEVER run into something I couldn't do on a mac.
Clearly the prices are a bit ridiculous, but in that aspect, a Mac is just a luxury computer. Is a luxury car really worth the money you spend on it? If it provides you some sort of utility, then yes.
Life is not all about getting the most "bang for your buck." Splurging on luxury products is what makes earning money so fun.
So, once again, I reference my main point; it comes down to preference.
