I'd be tempted to use one of these as a device which simply displays a custom written webpage which fetches and displays information. Once you've got it running it does nothing other than display a webpage. Put it on the desk, plugged in constantly. It could show my calendar or weather/traffic data.
Generally more. And they don't come with integrated WiFi or enough CPU to display anything on their own.
I'm trying to figure out if one of these would be useful as a wireless display for data that updates once every 5 minutes or so.
I live at a retreat center in the Cascade mountains, and we've got all sorts of diagnostic data about our hydroelectric generator and furnaces that would be useful to show.
I'm presently the IT Coordinator, which is an odd mix of Windows Systems Administration, Network Administration, and Website maintenance. (Sooner or later maybe some web development.)
