Contrary to recent rumors, it's not Palm's first Linux smartphone, and no, it's not a competitor to Nokia's Linux-based N800 Internet Tablet. Rather, Palm today unveiled the Foleo, which it's calling a 'new class' of mobile device. The device is designed to expand the email, Internet, and productivity application capabilities of mobile phones such as the Palm Treo, by adding a full-size keyboard and a larger screen. Company founder Jeff Hawkins predicts that the Foleo will be more successful than Palm's original Palm Pilot, which he designed, and more successful than its current Treo smartphones. He touts its simplicity: 'Press a button, it's on. Press it again, it's off. There are no other modes.'
