> Thunderbolt

I think you've picked a terrible example. I had to buy this very adapter yesterday, and I slowly start to wonder if I should've bought the USB one instead. It looks almost the same and doesn't prevent me from connecting an external DVI screen like the Thunderbolt adapter does. Maybe there's a Y-piece, but it'll certainly be another $29 or more.

It's largely intended for the retina MacBook pro, which has two thunderbolt ports, but I do agree -- many of the early peripherals seem to lack support for daisy chaining. As for the USB version... the thunderbolt one is much faster. File transfers at over 900 Mbps from the one testing report I've read so far.

I'm not fully convinced that there's much advantage to the USB one over just using wifi, except where the latter is unavailable.

The USB ethernet adapter is MUCH slower than a good 802.11n wireless connection, at least on my Air.

It's relieving to hear that the TB one is technically superior, but I don't see how it is intended for the MBPr - it is a checkbox in the Apple's MBA order form as well, along with all the other TB adapters which are mutually exclusive.

And even if the USB adapter is dog-slow, it's all I'd need onsite with clients (email, Skype chat). I'm still not sure if I made the right choice in the long term :/
