Apple

That would be your belief that it's not unreasonable to have to physically pick up and upend a desktop computer in order to turn it on. For the rest of human civilization, the concept alone is ridiculous.

No. It's not Apple's fault I configured my desktop to be efficient and ergonomic. It is their fault that they first made a large screen iMac (with an inaccessible SD card slot on the back) which was best suited for my needs, then discontinued that product which required I replace it with a Mini (and third party monitor equalling more than the price of the iMac), put the button on the Mini which is nearly impossible to feel in the first place, left out an SD card slot requiring that I purchase accessories to reasonably use my computer for computing, and then created a replacement product which requires unplugging things from it and physically lifting it up to turn it on, hindering the ability for a reasonably efficient desktop configuration to be upended so they could save a couple dollars on their product.

Please, you can feel however you want about this but it's an objective fact that this is not a reasonable location for a computer power button. I really don't care that much other than the fact that that I'm already prepared to not replace my current Mini with another Mini. The Studio Mac will probably be my next computer because it reasonably has a power button in an accessible-ish location and comes with an SD card slot; even though it's far more computing power than I'll ever need and more than I can reasonably afford.

I would imagine you also believe it's "reasonable" to forgo an SD card slot in favor of plugging your camera into the computer or having to purchase one or more accessories to reasonably use a desktop computer to add files to it.

Edit: I will note, to Apple's credit, they put the headphone jack on the front. It's sad how awesome something so obvious can be.
