Google has also made its own Wi-Fi phone

According to Engadget, Google would build its Wi-Fis phone with Alpha Networks in Taiwan.

The device a For Skype phones would work similarly, meaning that neither a SIM card nor a GSM network would be required. It is envisaged that the phone would connect to the Google Talk network using a wireless internet connection, allowing us to call friends who also have such a mobile phone or run a search engine chat on their computer.

According to the source page, Alpha Networks, a manufacturer of Internet communication devices, is also planning to integrate GMail's mail system and video calling capabilities into the device, which is likely to lead to the release of Google Video Talk. With this feature and the introduction of the phone, the chat program clearly wants to be a rival to Skype, the only question is whether Google Talk, which is not yet very popular, can seduce users of better known and more widespread messaging applications.
