As Satellite Radio gains momentum, handheld receivers are beginning to enter the market. Delphi has released its MyFi xm2go XM receiver as one of the first into the burgeoning arena with a slightly pricey, but competent handheld unit. The reviewer was impressed by its size and included accessories bundle, but found minor difficulties getting a clear signal inside a building or close to steep natural formations, a problem with all satellite-based technologies. However, a built-in hard drive and 5 hours of battery life per charge ensures that during periods with no power, the music is non-stop. Signal was fine in urban areas, since XM uses repeaters in cities, similar to cell phones. The integral FM transmitter was a bonus, though signal worked best while fairly near the FM receiver. Similar to other XM receivers, the song and artist currently playing are displayed on the screen, but the xm2go includes a memory button to store that information for later retrieval. Accessories bundled were extensive, including the requisite cradle/charging dock and AC adapter, but also in the box were headphones, home and car accessory kits, belt clip, carrying case and a remote control. With a built-in rechargeable battery and antenna, this will be a tough act to follow.
