Ipod Touch it's great it has so many applications, heres another.
Use Your Ipod Touch/ iPhone as Wireless Monitor
This is also great if you have an old laptop, to make it faster use a cat-5 (ethernet) cable.
All you need is:
iPod Touch/ iPhone- with vnc client (I use VNC lite)
Apple Macintosh
Screen Recycler

Step 1: Screen Recycler

Once downloaded install it and look in the folder then open screen recycler.
It will ask if you want to buy it, I didn't I clicked Buy Later, the demo mode is unlimited but you only have 20 minutes a go.
Take note of the ip address and the port.

Then go to the ipod/iphone and type the ip address on the screen recycler window and change the port (if necessary).

(6900 is the default port)

Step 2: Finished

Now your ipod/iphone is a working second monitor drag windows from monitor to monitor.
It is great for those with a Macbook or other that has only one display out and want more than one.
