LOL - I told you I use Office as well. The only problem I've ever had with any software - with Word, and after following the advice on the phone of a Microsoft Tech, caused a fatal error in the upgrade board of my older machine. Microsoft was quite upfront about the bug that happens with Word - has to do with some of the text box and publishing/page layout type uses. Not a figment of my, or any other Mac user imagination.
You're lucky - & clearly vigilant at never having had a virus, or glitch. Never a glitch with any of your Windows OS? That's really unique - you should call Redmond and get them to do an ad featuring you.
MS products - certainly not cheaper. PC (formerly DOS) based machines - sure - cheaper. More often replaced, as well. Sure, MACs can be more expensive, but you have to be careful with your comparisons of qualities and cost - as PC "speed" is measured differently than processing speed on MACs in most parlance. The technical journals will put them on the same basis - as does Consumer Reports - showing the MACs as faster. We all pay differently for what is included with a machine in terms of OS, additional software, etc. OS software for a MAC is less expensive than MS Windows variants - especially as upgrades come along regularly for free, and totally new versions aren't pricey at all.
I think it depends on what you want to do, what your use is, what your level of patience vs impatience, how straightforward the set-up is, and functioning are all things that affect a computer decision. Windows - the MS imitation of the MAC OS. That's where it came from, and has continued to imitate- just not as well. Not that it's not a product that works for people. That's the history - and historically the root of why long-time MAC users will slur upon Bill Gates.
