I'm, with Jerry on this one, but the wife really likes her Macs. She does graphics design and learned on a Mac, so that is what she's comfortable on. When we got it, I told her that she was on her own as far as configuration and such, but that still doesn't stop her from asking me whenever something comes up, so being the nice guy I am I do what I can (but I do grumble and moan the whole time
). I am NOT a Mac person because of their high cost vs their "meh" hardware quality (they tout their hardware as being better, but nothing I've seen justifies that claim). Not to mention Steve Jobs' god complex; the guy acts like he and his stuff is the answer to the world's problems. The interface is a customized Linux so nothing special there, and the platform does have a smaller application base (mainly gaming). They do have a nice design, but I'm not willing to pay extra for it. For me, I'd rather have a PC with better yet cheaper parts, and replacing things is not as expensive and problematic.
I'm not saying Windows is better; I'm beginning to really dislike Windows and Microsoft's approach. They release a new OS before the previous one is fully fixed. To me, an OS is supposed to simply operate my system stably and with minimal resource hit. I shouldn't need a dual core CPU and 4GB of RAM just to run the OS decently. I think the processor and RAM requirements should be driven by what applications you run (gaming, video processing, etc), not by all the eye candy, fancy tricks, and making the OS so it protects the user from themselves.
Jerry, as far as getting a new box, I'm with you there, but like I said, she wants a Mac. I suppose I could shoehorn the Mac OS on PC hardware, but that's more trouble than it's worth. Also, I can tell you I will be replacing my ~7 year old PC (which has had fewer problems) before we replace her ~3 year old Mac.
