I only started using a computer back in 2004 when I had my own shop, and not knowing any better, I spent £1800 on a fairly simple HP set up which included the hard drive, monitor, keyboard, mouse, printer, virus stuff, and of course the edition of XP and Office.
Everything involved with it was hard work, and required me swearing a lot and asking people for help! Also, I had to keep paying for the anti virus software.....
3 years later, I had closed the shop and taken the PC home, a friend had started working for a Mac specialist, and he was telling me about the differences, and then he got one, which I used, and loved, and I found that I COULD use it - which is the major difference to me.
I stumbled across a facebook ad for a secondhand eMac, it cost me £80 and even after defragmenting the PC, running this that and the other, doing countless virus checks, my £80 eMac was outperforming the PC hands down. I've never really struggled to do stuff (ok so check my post recent post re an email issue to contradict that!) whereas doing simple tasks on the PC would defeat me! A couple of years ago I bought a secondhand MacBook for less than the cheapest of cheap brand new Windows laptops. My mums HP laptop lasted about 12 months before it got to the point that it was 'too uneconomical to repair' (battery knackered and running slower than Peter Griffin doing a marathon)
So anyway, I've been using Macs for 3-4 years now, I've never paid a penny for virus protection, they work, you get the most amazing customer service I could ever imagine from any company that operates today - seriously, I am very critical when it comes to customer service, and what I expect from a company that takes my money! * Apple have so far exceeded my high expectations.
Macs work, and Apple look after you. Why would I change?
* Not that Apple have MY money exactly, I've always bought secondhand.
