I design applications for an entity that leverages PCs. This question was often asked of me and I regularly discouraged ownership of a piece of equipment that only a small percentage of the population was using.
When faced with a buying decision, I thought it professionally worthwhile to have some familiarity with "the other" environment so in 2009 I purchased an IMac as my home computer.
I now know that I was a totally malinformed idiot. Five years later, my Imac still takes 36 seconds to go from a cold boot to surfing the net. I haven't had to invest a moment in calls to Apple, virus protection, uninstalling/re-installing software, or dealing with peripherals that didn't seem to communicate with this machine.
Congratulations on your purchase. :)
