This PolarIP Atomic Skype phone is the first cordless Skype phone designed to work with both Macs and PCs. This isn't like the Standalone Skype WiFi phones that don't require a computer to operate. The Atomic plugs into your Mac via the base station and communicates with the cordless handset wirelessly.
The handset has an LCD for displaying your Skype contacts and numbers, uses the 2.4GHz band and has speakerphone for hands-free chat-chat. It's available for 49.99 ($92) on the Skypestyle site. PolarIP also released Mac drivers for their two cheaper handsets, the PowerME and the EZY, which are 29.99 ($54) and ($35) respectively.
