Unpacked and in the process of installing Logic 9 and X plus the extra content.
The display is quite an upgrade from the previous external monitor I used in terms of picture quality and impressively large for a 21.5.
Having an external keyboard will be super nice. I wasn't so sure about the mouse when I saw it didn't have a scroll-wheel. But then I noticed that it was actually a tactile surface in its own right. :)
Furthermore, I just went from 2 USB ports to 4. On my laptop, the ports were allocated to my audio interface and the hub. Now I can discard the hub - external hd, audio interface, midi keyboard are all hooked directly, which mean everything becomes better/faster just with that and since the mouse and keyboard are wireless I have a port left.
The extra bonus is that my MacBook Pro becomes portable again. Not only that, but I can use it as a synth and effect host, and to control my POD HD.
Incidentally, I've had the opportunity to help out one of the Apple folks at the store which a customer asking technical questions about Logic and digital audio... Always nice. :)
