Specs aren't the issue: You can always get a superior system for the money (on paper) as a PC as compared to Apple's offering. The issue is one of quality. My own recent Dell experience is a good example.
I bought a replacement for my 2007 Dell XPS laptop as it was getting old. I decided to try out an Inspiron. Okay let's not even talk about that, except to say that it quickly went back and a new XSP laptop arrived at my door. I was relatively shocked how similar it was to the Inspiron, how many aspects of quality have so badly degraded in the product line since 2007. Instead of a keyboard, we now get a button board. Instead of a nice, glossy screen that resists scratches, I now have a matte finish screen with loads of noticeable imperfections in it. And that's just the surface issues.
Now for all I know, Apples can have crapped-out similarly, but that's not what I hear from my family members who have drank the Kool-Aid.
