Just as another point of view, I have to say that there is a significant advantage to Apple hardware from one perspective (at least in the last few years) -- not so much in the raw processing power per dollar, but in the engineering of each device. I have several Mac Minis now; these things are wonderfully reliable, they run relatively cool (particularly the newer versions), and they run absolutely silent. Even if you push them enough that they have to run the internal fan at high speed, they still only make a quiet "woosh" noise when running.

My mother replaced her Android tablet last year with an iPad. The Android tablet (from a cheap manufacturer, admittedly) couldn't last two hours without being plugged in, and eventually started rattling as you moved it around as something had broken off internally. The iPad lasts her all day without needing to be recharged, and is built like a tank.

I really do have problems with Apple's penchant for designing non-upgradable computers, and I doubt I will ever purchase an iMac (as I think integrated screens are the absolute wrong way to go for a desktop computer). But Apple hardware isn't necessarily overpriced.
