From Windows to Mac--anyone done this?

If you compare the price of a Mac to a PC, it will appear the Mac is much more expensive. However, if you look at the total cost of ownership, it becomes more competitive. What is free (or unnecessary) on a Mac that you pay for on a PC? Operating system, spreadsheet, word processor, various built in utilities, anti-virus software, anti-spyware, anti-ad, etc. some may push back on the anti-virus. I owned PCs before buying my Mac and would never have run it without an anti-virus application. I've owned my Mac for five years and never installed an anti-virus application on it (although I do keep good backups just in case!). I could usually get 3 or 4 years out of my PC before I needed to replace it due to hardware age, software incompatibility due to obsolescence, etc. I have had my Mac for five years and it still runs very well and is not in any danger anytime soon of becoming obsolete. But, as one poster already indicated, Mac/PC is a preference. Neither is going to satisfy all of everyone's needs. As I said before, I wanted simplicity, interoperability, and a lower total cost of ownership. As a PC user dating back to pre-IBM PC days (right, that's 1983), I believe I am getting what I need from my Mac.
