I've used Macs from 1983 and stopped in 1996 believing that maybe I was getting ripped off since everybody in the MS-DOS and Windows world kept telling me that I was overpaying for my Apple comps. Apple Macs in the 80's and early 90's really were expensive back then.
I bought and made exclusively Windows machines since 1996 and got quite accustomed to them. I even derided others for using Apple Macs.
I then grudgingly bought my MacBook Pro 1 year ago only because I needed it to develop apps for the iPhone. I bought the older discontinued model with the silver keys trying to save some money on something I did not really expect to be worthy of normal use.
After I got through unlearning my Windows habits (Microsoft had reversed the locations of the graphical controls from the original positions Apple had in the 1980's OS e.g. Apple menu bar on top vs Windows task bar at bottom, window controls on upper left for Apple vs upper right for Windows, etc) I realized that I had forgotten how "easy" and effortless a Mac user experience could be. I was blown away by the speed of Mac's OS X startup from both cold and sleep as well as the crazy stability. The design of the MacBook Pro was truly ingenious. The touchpad use was phenomenal and something I never would have even thought could be amazing coming from the Windows world. I had been thinking of tech specs mostly using/building PCs and not the subjective quality of the total user experience.
I had just gotten used to
Microsoft's blue screens of death and all the hours I spent in the past troubleshooting.
Windows machines may be cheaper, but only if your time isn't worth much. At this stage of my life, I can't afford NOT to use a Mac/iPhone/iPad.
As far as security, your odds will be better with a Mac running OS X.
