Cell phones may someday send landline phones into retirement -- but we're not there yet.

In fact, there's a technology to know about if you're in the market for a cordless phone. It's call Digital Enhanced Cordless Telecommunications (DECT) and while it's not new in and of itself, its use in cordless phones in the U.S. is.

The key advantage to DECT is that it plays well with others. It won't interfere with WiFi, a wireless keyboard or mouse, a home security system, a baby monitor, or a microwave.

We've been testing a DECT phone from Panasonic and it's lived up to its promise: interference-free, 17 hours of talk time, and comfortable to use.
