I've used MS PCs since first introduction, still do, but NEVER on the internet. A few years back after experiencing an especially frustrating situation with my PC, I went out and bought an iMac. Since that time I've never seen a pop-up and have never experienced any kind of worm, virus, or whatever .. and .. I've never had to pay a single penny for anti-virus software. I've never seen lockups, freeze-ups, or issues of that type of any sort. And loading new software, including operating systems, is always a breeze. And by the way, the time machine automatic backup feature is worth its weight in gold.
I do so appreciate finally having a frustration free computer. To me, the Mac is very much worth its higher price.
Now that I've experimented with using my TV as an alternate iMac monitor (works very well) I'm going out and buy one of these new Mini Macs for just that purpose.
