Palm just released their Linux-based Palm Foleo Mobile Companion. It is a device that has a 10" screen and full-sized keyboard that syncs with your treo smartphone. It is akin to the Nokia Internet Tablet N770 and N800 but obviously bigger. The Foleo comes with an e-mail client, Opera browser, MS Office file format compatible editor and a photo viewer. Connectivity wise, the Foleo comes with bluetooth and WiFi support.
It is coming this summer in the United States and carries a special introductory offer of US$499.
