Microphones. The iPad has multiple mics to help with noice cancellation and for Hey Siri functionality.

I want to know if the blade SSD is the same one as the MacBook Pro has, to where you can interchange their drives.

I'm also curious about where the WiFi antenna is. Is it still only behind the Apple on the back, or is it different in the 3G model from the WiFi only model?

Is it possible for the various connectors to be labeled/identified? I'm trying to test a lower half but I don't know what exactly is missing, trying to figure it out by what's not plugged in.

Citaat van luke:

I think Apple may be talking input power, while we're talking output. An input of 365 watts and output of 310 watts is 85% efficiency, which is typical for a good power supply.

And I learn something new from this site yet again. :)

The tech specs for the 27" iMac say it can be up to 365W, so I suspect the Quad Core variant has an even larger power supply.
