The PlayStation Portable (PSP) is a great games handheld (I play mostly LocoRoco and Patapon), and I discovered recently that it's great for work too.
The PSP has a built-in Web browser and Wi-Fi capabilities. I set up a simple Web server on my home PC, wrote some scripts in .NET, connected the PSP's Web browser to my Web server, and I quickly transformed my PSP into a wireless display panel.
My PSP sits right beside my bed and shows me the current time and my unread e-mail messages. The Web browser refreshes the page periodically so that I can see the latest e-mail messages. The screen is bright enough to be visible at night, so I use it as a bedside clock and can peek at urgent e-mail messages in the middle of the night.
I have been running the PSP continuously for the past month without any problems. This setup should work with the iPod Touch, too, except that the PSP screen is larger and easier to read.
One of these days, I'll add more stuff to my PSP display, perhaps weather, stocks, uptime of my servers...
