Anyone can sell a laptop docking station for $1000.
Only Apple can make something that seems almost worth it ...
With just one cable, connect any Thunderbolt-enabled Mac and get 27 inches of high-resolution screen space, high-quality audio, a FaceTime HD camera, FireWire 800 and Gigabit Ethernet ports — and a Thunderbolt port you can use to daisy-chain additional high-performance peripherals such as hard drives and video capture devices...
... The Thunderbolt Display includes a MagSafe connector that powers and charges your MacBook Pro or MacBook Air. The connector sits on your desk, ready and waiting. No need to unwind the cord to the power adapter that came with your notebook. Leave it exactly where it is, in your bag.
Yes, it's insane.
And yet ...
If I wanted the best of all worlds, and I was single, the combination of an 11" MacBook Air and the Thunderbolt display would almost make sense. Hang storage and peripherals off the display, plug in power and Thunderbolt cable, and the MacBook Air becomes a serious iMac contender. Disconnect and travel with an ultraportable.
A 27" iMac is $1,700. An 11" MacBook Air is $1,200. Together they come to almost $2,900. The MacBook Air and the Thunderbolt Display together are "only" $2,000. Really, cheap by comparison.
Heavens, but Apple is Satanic.
PS. Anyone remember the Powerbook Duo? Aka MacBook Air 1.0, but with 3 much cheaper docking station options.
