Feh. Silly thing...you need a Game Boy!
Or even a Nintendo DS--those look more like a PDA, so people will think you're working!
Or, since you're babysitting servers, they'll think you're fiddling with a Smart Phone.
See? I thought the whole thing out for you--if they say, "Hey! Is that a Game Boy? I think one of my kids has those. In my summer home. Or maybe that's the thing he left on the company jet last week when we flew to Tahiti...", you just sneer and say, "Pfft! HARDly...I'm configuring Wi-Fi for the DS." <--sounds like you're talking about some server or something.
