At $1,600, Sony's new Vaio TP1 Living Room PC, announced today, might be a little pricey for some of you, especially considering that it doesn't have an HD optical drive. Still, we suspect that its Roomba-like design might be charming enough to help it find a way into many living rooms. It does include an HDMI-out, so you can at least hook it up to your HDTV. It will be powered by Windows Vista Home Premium and an Intel Core 2 Duo laptop chip (which model is unspecified). Other specs include built-in Wi-Fi networking, a standard-definition, dual-layer DVD burner, a media card reader, a 300GB hard drive, and a TV tuner. Look for it to show up in retail stores around March.
