I was an IT manager. Me and the 5 folks on my team were responsible for about 500 Windows machines, 500 Macs, thirteen location inter-office connectivity (routers, hubs, switches), printers, file servers, remote and internet access, email and pretty much anything else that had anything to do with computers or networks at the company.
Of the five people, 1 was the network admin responsible for the file servers and email system. He also was an escalation point for the more difficult Windows issues. Three were dedicated to Windows desktop issues. For every 1 Mac trouble ticket that came in, we would get 5-6 Windows trouble tickets. One of my folks was dedicated to Mac issues, but had enough free time where he started picking up Windows issues. I was an escalation point for the Mac issues - but also picked up some of the Windows issues because there were that many.
My strongest "loyalty/bond" with Apple is purely financial. While they did cost more (back then) to acquire, their support costs were substantially less and they lasted years longer. The last thing I felt like doing when I got home was to do more troubleshooting - so my hard-earned money was spent on Apple gear... My son and wife rarely required assistance. Macs had (an in my opinion continue to have) a lower total cost of ownership.
I have since moved on from that IT Manager role - but I continue to buy Apple products for home use. The only traditional Windows machine in the house is the one my current employer makes me use. While my employer's IT department does not support Macs, I regularly remotely access the corporate intranet and email - and am much more productive doing work on my Mac than on the work-issued Windows machine. (Their stance is, if I can get remote access and work done on my Mac without IT's support, that's fine, but I cannot use them for any assistance. Interestingly, it took me less than an hour to get my Mac in remotely - but an "experienced" IT person a couple of days to get my new Windows machine in properly).
On top of that, Apple's form/function designs are head and shoulders above what the Windows world has ever made. I have paid a 50% premium over name-brand Windows machines because I know (and I had the spreadsheets to prove it) in the long run, the Apple computer TCO would be lower. Today, I would probably put a 20% premium on it, though I have done recent comparisons, and when similar-equipped name-brand machines are compared, the Apple machines are the same as - or less than - a comparable traditional name-brand Windows based machine... and I feel satisfied knowing I am making the right return on investment decision. Though today, I suppose I *could* just run Windows on the Apple hardware... but why waste a perfectly good machine for that?
There is only one other company with which I might consider "similar loyalty"... I bought my first product from them in 2003. Earlier this year, I bought my second Cadillac CTS... I'll get back to you kn how it makes me feel... Up until now, I hadn't really thought about it.
