Last time I was in BestBuy the cheapest Mac was north of $1000. The PC's started at about $350. That's pretty close to 3x for most of us.
Macs are nice machines ; but they are over priced. Lots of folks don't have a $1000 plus to spend on a PC of any type.

But for an equivalent configuration, a mac might be only a few hundred dollars more.
You really get what you pay for with super cheap PCs.
It's amazing how much laptops have improved in the past few years. My first laptop was a low-end Dell that I bought for $1000 in 2003, I think. It was OK for a while, but after about a year it started to feel painfully slow. The slowness was a combination of a cheap CPU (Celeron), low RAM, terrible Intel integrated graphics, and a slow hard drive. It got about 2 hours of battery life, and it lacks features taken for granted in modern laptops (like integrated WiFi). These days $1000 gets you a laptop fast enough that most people wouldn't be able to tell that a more expensive one is any faster.
A year or two after I got the laptop, I replaced the it with a desktop as my primary computer, and the desktop served me well. I got a mid-range Dell, I can't remember how much I paid for, but it wouldn't have been much over $1000. The desktop lasted me until 2008, at which point I got a new laptop for college (my parents paid for that). In the 3-4 years I had the desktop, it never felt as painfully slow as the laptop. The only time it was ever a problem was when I tried to do anything CPU-intensive such as video encoding, which would just take an impractically long time (like 8 hours per hour of video).
My biggest mistake was probably getting a Dell for my desktop instead of building it myself, or getting a laptop instead of a desktop to begin with. As I wanted to upgrade, I had to get a new Motherboard because Dell's was very limited. Dell's case is proprietary, and standard motherboards won't fit, so I also had to buy a new case as well. If I had built the computer to begin with, I could have just upgraded the CPU with the money I used to buy the motherboard and case.
Later on I replaced the power supply and upgraded the RAM to 4gb. Just this year I finally upgraded the CPU from a Pentium 4 to a Core 2 Quad, bought a video card that can run Windows 7, and bought a fast new hard drive some money I got from selling a hard drive controller board on eBay (it sold for more than the whole drive was worth). There are finally no original parts in this computer. Since I saved all the old parts, I ended up with the original Dell computer alongside a new one! I sold the Dell for about $300 on eBay, which seems like a lot more than it was worth, but I'm not complaining.
I am using currently the computer as a Windows workstation alongside my Mac laptop since it makes it easier to run Windows-only programs. It's not really necessary with virtualization and dual booting, but it is convenient and makes a good platform for experimenting if I don't want to mess up my laptop. It's also really fast.
Computers are kind of a hobby for me.
