You wonder how many iMacs are being repaired or replaced due to "operator error" with hard drive replacements.
That's the only thing that makes sense....
Though I will say, the prospects of cracking into an "All in One" for user customization seems a little odd....that's what towers are for.
The problem is the only tower that Apple makes starts at $2500. Most people can't afford this.
I have a Mac Pro myself, but I'm still pissed off at Apple for not offering an "enthusiast" machine at non-stratospheric price levels.
