[SOLVED, mostly] Arch on Apple MacBook Pro 15-inch with Retina Display

Question

I've been looking into the Apple MacBook Pro. Of course, I would want to get rid of Mac OS X and load up Arch. Please tell me if the following will work out-of-the-box or have workarounds:
WiFi
Ethernet
Sound
Touchpad
Keyboard
Charging
Bluetooth
Graphics Card
Webcam
Microphones
USB 3.0 Ports
HDMI Port
SDX Card Reader
I know the high DPI display shouldn't be a problem since GNOME Shell now supports those, but I want to be able to use all of the above things. Also, please let me know if there are any other problems to look out for. Thanks.

Answer 1

I can't comment on your specific model, but IMHO, getting a Mac (especially a Mac laptop) to run Linux exclusively doesn't make much sense, for the following reasons:
Apple's EFI implementation is weird, and some features (most notably the ability to upgrade the firmware) can be done only with the help of OS X. As a practical matter, this means that you'll either have to use exotic tools like the Linux version of "bless" or boot the computer in BIOS/CSM/legacy mode -- and even then, upgrading the firmware will be a hassle, should that become necessary. Booting in BIOS/CSM/legacy mode is the easier path, and there's nothing wrong with doing it that way, but as the industry is moving away from BIOS and toward EFI, it means that either you'll be going in the other direction or you'll need to struggle with a Linux-only EFI-mode installation on the Mac.
Hardware support in Linux for Macs is a bit weird, in part because of the preceding issue (the weird Apple firmware). I realize your question is aimed at uncovering specific answers about this topic, but as a general rule, Apple hardware seems more trouble-prone under Linux than standard PC hardware. Also, note that hardware support can vary depending on the mode you use (BIOS/CSM/legacy vs. EFI). Video hardware can be particularly troublesome on some models, with BIOS/CSM/legacy sometimes working better.
Mac mice (including laptop trackpads) are 1-button devices, but Linux works best with 3-button mice. A 2-button mouse can do in a pinch. Using a 1-button mouse with X requires applying unusual workarounds involving the use of keyboard keys while clicking the mouse button. Although this can be done, it's an extra hassle, both to set up and to use. On a desktop computer, of course, you can just replace the mouse, but this isn't always practical with a laptop.
I haven't checked pricing recently, but Apple hardware tends to carry a price premium compared to similar hardware from other manufacturers.
Although most of these issues (with the possible exception of price, if you're on a tight budget) aren't really critical by themselves, they combine to create a rather unpleasant combination, at least when considering a Mac exclusively as a platform for running Linux. If you wanted to dual-boot with OS X, things would be different, of course, but personally, I wouldn't buy a Mac as a Linux-only computer.
If you've got specific reasons for wanting a Mac, perhaps you could post them here. Although I personally haven't shopped for a laptop for a while and so can't offer specific suggestions, somebody else might be able to suggest alternatives that would do what you want.
