Pros: Very simple to use. Worked out of the box with no setup required. Includes all needed cables. Compact hardware.

Cons: Mac software not on CD. Requires USB port for power.

Overall Review: Thunderbolt and Mini Display ports supply power so there's no real reason to require a separate power source. That being said, why use USB to power the unit? I would much prefer a dedicated power source so as not to consume a port on my computer. Aside from that (admittedly minor) gripe, this thing is great!
