I've had PCs since the DOS days. Run every OS, up to Win7, currently in use on my Dell Studio 17 laptop, which I added various options to up to $4,000 price tag.
It works perfectly, has no crashes, is connected to the internet/www constantly and is protected by AVG.
My wife/daughter use Macs because I'm unwilling to work on their PCs, and all the issues they create from not knowing what they're doing. So they chose Macs. Good for them. I told them, any problems with your macs don't come near me, I have no interest in working on or fixing them, ever.
Coyote machine has summarized exactly my feeling about Macs. If you are a real computer guru, and are willing to put a lot of time and energy into your computer, Windows is the way to go. And it is less expensive.
OTOH, if you want to just run your business with the computer and spend your time on your business instead of of your computer (which has never paid me a nickel) pay a little extra up front, and you will not have to put that time into your computer. You will put it into doing what is fun and profitable.
I have used Macs since the late 1980s. When my wife and I were married in 2000, she was an ardent Windows user. Wouldn't touch a Mac. She is a University Professor and consults on the side. She frequently had consulting reports which were due on a specific date. There were 4 or 5 times that she had a report due in about a week, and her computer went on the fritz. The only way to get the report out in time was for her to buy a new, top-of-the line computer. I was always able to get the old one up and running with a few hours work spread over several days, but by then she like the new one and would give the old one to one of her better students.
Back then, computers were more expensive than they are now, and she would spend about $2500 every 8 or 9 months on a computer.
Then I convinced her to take a Mac class, and she got a Mac computer. No more computer crises, it just kept running and running. A lot less stress in our lives.
Now, she happens to like new computers and gets a new one every 2 years or so, but she earns a lot more than that from consulting.
Had an i-phone. Went to a Samsung Galaxy S5 Active and never looked back. Don't like Apple's way of selling their 'help' access, and their general arrogance. Had me have to pay for price of a new phone on my credit card while they were 'fixing' my broken one...RIDICULOUS! Why would I want to keep a broken phone? They refused to swap it out without full payment in advance. I won't buy any of their incredibly overpriced gimmick products ever again.
I have had iPhones ever since they first came out. I buy Applecare for them, and if anything goes wrong, I take it into an apple store, and have always been handed a new (well, a refurb) phone. It takes about 20 minutes total. And, best of all, I drop the "insurance" the phone company wants to sell me for $6.95/month in favor of the Applecare. I have to pay it all at once, but it ends up costing less over 2 years.
When my laptop developed a problem, I had to send it in for repair. They do not give loaners, but told me that if I had a credit card, they would sell me a brand new one, which they would completely refund anytime in the next 30 days. I was skeptical at first, but the computer was back in less than a week, and they took the now "slightly used" one back for a full refund. Cost to me? Nothing. I see nothing at all unreasonable about this policy.
Now here is a secret. They sell the returned computers as refurbs on their web site at a reasonable discount.

Anyway, the bottom line is that I have use Macs for over 30 years, and they have never let me down. The company I worked for switched to Windows about 10 years before I retired. Hated every second of it, but I could make them work, since the company had an IT department and I had unlimited free tech support over the phone from someone who spoke American English as a primary language.
The dirty secret of computer makers is that if a large company buys a large number of computers they get tech support from the US or Canada, if a consumer buys a Windows machine, the tech support is from India. The language they use is English, but it is not colloquial American English, and it is very difficult to understand. Especially with a complex problem. All of the Apple tech support for the US is based in either the US or Canada, and the people are much easier to understand.
