A GSM Desk Phone?
I suppose in a world where everyone has a mobile phone and no landlines, it may be desirable to have a fixed phone somewhere, yet continue to use the mobile phone network. In that case, you might want something like this: The FW-290 GSM Phone from Perfectone.
They appear to make both North American and worldwide versions of this handset, supporting either GSM 850/1900 (North America) or GSM 900/1800 (Europe and most everywhere else). It supports all the standard calling features and sports a nice, big antenna.
While the Perfectone folks emailed me the information about this device, they did not provide a release date or pricing.
