Trying to work on a macbook pro 15' without it was unbearable. This makes it so you can have your session up & the mixer. Life is so much better now with this now. Yes, it was worth every penny.
The best monitor and best connection for all. Connected by Thunderbolt cable, you have 3 USB, another thunderbolt (so you don't loose your main connection) firewire for all my old hard drives and ethernet port. With my Mac Book pro is the best.
