I asked for this for my birthday - the problem with boutique keyboards is that they're practically impossible to test-drive. It's a great keyboard, just not what I'm looking for. Cherry Brown MX mechanical switch, two USB 2.0 ports, "silent" (quieter than a clicky keyboard, but still louder than your typical MS/Logitech model)
