Internet telephony is a growing phenomenon, but regardless of the service you choose to use, you have to be a short distance from you computer at all times. Either you are tethered to the computer with a headset or close by to accept the incoming call.
Netgear has teamed up with Skype to create a Skype-enabled wireless phone that you can use without a computer. The Skype Wifi Phone resembles a cell phone, but works over your wireless internet and allows you to call other Skype users for free and regular phones at a small cost.
While the computer-less feature may not warrant its purchase solely for your home, as you likely already own a computer that prompted your wireless internet connection in the first place. However, the possibilities for using the phone away from home are promising. If you are traveling or just out on the town, all you need is a wireless internet cafe or hotspot. This could be particularly useful when you're out of the country, where calls are more costly. Using the phone at home would be convenient, but might not necessarily warrant the purchase.
If you are feeling a bit skeptical about a device dedicated solely to an internet phone service, Netgear has just released a dual internet/landline version that might make a more practical tool for the home.
