Haha the delusion of integration! It took a third party for Apple to do their testing and analysis for them after the product release.
Isnt that how apple do all the testing,
Apples process is something like this
step one, J.Ive design a case nothing with a reasonable performance can fit into.
Step Two, the hardware engineers go out and shoehorn whatever they can find that can kind of fit into that case.
Step Three, Apples marketing team has to spin the reason you can get a PC for a tenth the price with 4x the power almost solely on the J.Ive designed case and a load of specs that don't work yet and might be patched in later.
Step four, build a giant ring shaped building to put all the money in the middle of and swim about like Scrooge McDuck.
Now im not an apple hater, i love the OS, i just wish they would u-turn from this sealed unit lockdown, all our products are disposable, kick they are on , when its easier to replace the Harddisk in my PS3 when it fails than my iMac, something is seriously out of whack.
