I have been using the ATD now for about 2 weeks. Prior to that I had my 11" hooked up to a 27" Apple Cinema Display. Originally I thought what's the big deal with the ATD if I already have the ACD. After some more research and thought, I switched because of the following:
- The gigabyte ethernet connection on the ATD. Having a consistent, fast network connection makes me just that much more productive.
- Thunderbolt is a lot bigger pipe than the straight USB hub connector on the ACD. And I have noticed this when it comes to connecting external drives through the display hub. One of the external drives I use is an SSD with boot camp installed on it. On the ACD, the drive sometimes would lose its connection when I am running boot camp as a VM and have other extnernal drives connected as well. On the ATD now, those issues have disappeared. Yes, the ATD is not any faster per se, but the thunderbolt to thunderbolt hub connection can handle more throughput imo.
In general, the ATD is worth it for someone w/ the 11" if they work at a desk a lot vs. a more mobile person who don't want to chain themselves to working at a desk all the time. 27" of glass and aluminum isn't exactly easy to move around🙂
