Is there an alternative to AirPort Express in that you plug it into a wall and you receive a 802.11b/g connection? I would like AirPort Express, but I have no use for "AirTunes" and do not want to pay the premium everyone must pay for an Apple product.
Also, does anyone know about PowerLine technology? I read an article in the WSJ about it saying that you plug an AC adapter into a wall electricity socket, and it give you an ethernet connection (and some versions will transmit a wireless connection). Does this work very well and is there a monthly fee/does it only work in certain areas?
