As a computer programmer, which I believe that makes me more "tech-savvy" than the average person, I can honestly say that my PC and my Mac fill specific niches that the other fails to fill. I tend to do most of my work and coding on the PC. Primarily because I like being at a desk for that, with papers and what-not strewn about, and since I purchased all my software originally for PC, I keep upgrading it to that platform. I have a Dell XPS that's a couple of years old now, but specced out very, very nicely.
The MacBook Pro however is the machine I do my writing on and most of my pleasure-computing. To say it is a finely crafted tool would be accurate. Everything about it is geared to be pleasing to the eye and hand. The monitor is more gorgeous on the laptop than my other comp, and it's got a lovely screen as it is. The Mac display shows no pixelation or lack of ability to keep up with the data rate when playing any DVD, and the colors are sublime, not harsh. The sound is superior than any other laptop I have owned. No tinny little speakers in this machine. Watching a movie is on it is enjoyable. Granted I have a 17" monitor, because I don't want to squint at any small screen anymore. It has crashed .. once? My PC regularly needs attention to keep crap spyware and malware from affecting it.
Specs are one thing. Pleasure is another. From what I have heard CV say she wants out of the machine, I would recommend the Mac. It will bring her more than sufficient power and a lot of happiness while she is using it.
