Interesting Gadget Display is a small “USB-connected” box with a two-inch OLED-display, on which you can display a display of various system information. Starting from the clock and ending with data on CPU usage and RAM usage. And in the slide show.

This thing works under Vista and Windows XP. But, comrades with Engadget, having rummaged in the device descriptions, did not seem to find support for Vista Sidebar gadgets. However, and to hell with it, with support. And so good.
Information about the price and date of appearance of Gadget Display on sale yet.
