This was nifty, to put it bluntly. Maybe not the most practical thing, but I could see having something like this handy if you want something you can throw into your bag. Its probably also good for working with racked servers, I’d imagine, if a USB port is handy…. Though I suppose you’d also want a screen. Ah well, just an aside :).
