I don't know if you're being sarcastic or not :-)

That said, CPUs have gotten so cost effective that it makes possible something which has come in and out of favor for a while, which is a network of devices that do one thing co-operating as a larger system.

So lets say you buy your "iDisk" which is a storage brick that you can put on a short range wireless network. A couple of iPad monitors, a wireless Apple keyboard, and a wireless Apple mouse. You set up this box of stuff and arrange it around on your desk and it is essentially a "single" computer system perceptually which, running a development "app" could work fine for development.

We've been dreaming about this kind of system since the rumors were flying about the Apple "Brick".

The "brick" turned out to be the all-aluminum MacBook, being carved from a single piece of metal.

You'll need the screen to keyboard dongle to accomplish this.

Need at least three in order to emulate a dual monitor setup.
