As you can see, many products are available from a host of manufacturers, all hoping to capitalize on this explosive new market that's been created through the prevalence of MP3s and wireless networking. Keep in mind as you evaluate these technologies that many of these products are first generation, targeted at early adopters. Expect a few hiccups along the way. And don't count on the manufacturer and/or product being around forever. Fortunately, on the low end, you don't have to spend an arm and a leg to get a decent product; in a few years, when 802.11x is around and you can stream a DVD at full quality anywhere in your house from any of the machines on your home network, you won't feel like you wasted money in the meantime.
