Dell Home offers the Netgear Push2TV 1080p Intel Wireless Display Adapter, model no. PTV2000-100NAS, for $49.99. This $20 mail-in rebate cuts it to $29.99. With free shipping, that's tied with our mention from two weeks ago for the lowest total price we could find by $30, although we saw it for $14 less last summer. This adapter wirelessly transmits whatever is displayed on your laptop screen to your TV, up to 1080p. Deal ends March 9 at 7 am ET.
Note that this device requires a system with Intel Wireless Display (WiDi); click here for more information.
