This thing is just sick. I just went through the Pacemaker Flash demo and watched a video of Ritchie Hawtin playing around with this and I'm totally up for getting this thing. It's like having a portable version of Traktor without the laptop. 120GB of storage. Nuts.

Not sure how usable it will be. The one thing I've had a hard time with is using the on screen controls with mixing software. This is usually improved when you buy a piece of hardware called a controller -- essentially a physical mixer with wheels mimicking turntables that let you manipulate the onscreen controls of the software. The thing this has going for it is the tactile experience.

You'll have to shell out about $700 and wait until around Christmas time.
