This is off topic, but I have been using Apple computers since 1983, starting with an Apple II. I have used lots of them, and I have seen some defects, like a bad logic board, batteries go too quickly, and hard drives can crash.
On the other hand, they do not seem to get viruses. The OS is also much better, and I have to use PCs at work - so I am familiar with both types of machines.
All of them are made from parts produced overseas.
OS gets viruses as well, and has been far less secure then Windows Vista/7 for the past 5+ years, and running. Specially with Windows 7's release, OSX has been criticized for not providing adequate security/security support. OSX has been targeted for malware during this past year, which is the #1 risk now a days. With windows 7 support/removal tools are available, in fact Microsoft writes many articles for many exploits/malware from how they work, to how to remove them. Try looking for the same kind of support for OSX. Apple themselves took a "don't deny don't confirm" approach to a particular Malware infection, who knows how many clients were swindled because of this failure to act to protect consumers.
Not sure what you mean by OS is much better. It's off topic but meh. I've been acquainted with computers since I was 9 years old, and currently have a family business for computer repair, services, etc. I am very familiar with Windows and OSX as well as hardware for Apple and other manufacturer's PCs. I both fix, and build machines. Anything from building low end office machines to high end systems using water cooling, phase changers, to custom mod cases.
My #1 choice of OS would be modified ubuntu, for quick boot (approx 11 sec boot time, with mechanical hard drive not sure what it does with SSD haven't tried because with SSD in doing nearly the same time), however my #1 use OS is Windows 7 due to some programs I use, some neat features as well as better scaling for performance for both professional work, and gaming.
Both Apple/PC's are made with foreign parts, in foreign countries. There is not one manufacturer making computers here unfortunately.
Here's a few of the computers I've owned or own.
Dell E6500 Macbook Pro 13.3", that's my channel. Both were mine. Sold the MBP

This here was my pride and joy, Dell Precision M6500 workstation laptop. Not even going to mention how much it cost me. Built like a tank, with Accidental warranty and next day with onsite tech support. I also had the option of receiving parts and installing them my self due to my work. Sold it, got the Envy 17.

This is one of two Envy 17, Sandy Bridge model. I was one of the first to receive an HP Envy 17 using Sandy Bridge processors, as I was dealing with HP Research Lab, I had access to any product from HP, even if it was not released. Build quality wasn't that good, meh. HP gave me a damn headache. I had two of these. Running almost max specs. 8gb DDR3, 2820QM processors, 2x640GB HDD in RAID 0, 3D 120hz 1080P Display. Sold both of them, massive issues with the two laptops, and headaches with HP.

(My previous Thinkpad is on the left, It's a Lenovo T61 Thinkpad, nice laptop way better then any MBP in construction/quality.)
