I think HP should really show a picture of expanding a PC workstation versus the new Mac Pro which would result in a spaghetti junction of external cables, boxes and power adapters.

Also, I actually don't know any developers who are using the new Mac Pro, whereas before they would be excited and talk about the old Mac Pros. Are the new models selling well? Any start-ups using them? After the poorly received release of Final Cut Pro X, I imagine most video production folk went back to their PCs... and since Apple gave up on the server, enterprise and scientific computing markets, who is actually buying and using the new Mac Pros?
