MacBook Air misses half its thunder, still awesomely hot
What you see above are the innards — that is the motherboard — of the latest 2011 MacBook Air, dissected and displayed with love and care from the folks at iFixit.
A careful examination of the Thunderbolt controller chip at the top right has revealed that this is a different chip compared to the one used in other Thunderbolt-equipped Macs we’ve seen so far. This chip, codenamed Eagle Ridge, is capable of handling two bi-directional 10Gbps Thunderbolt channels and one DisplayPort output. This means you can connect only one display, that is, no daisy-chaining of displays here.
