Originally slated to debut before the end of 2007, the completely revamped version of Palm OS, which is found in Palm's Treo smartphones and PDAs, has been delayed until sometime next year. The company has reportedly been running into development slowdowns building the new Linux-based platform.

Palm will continue to make devices running both Windows Mobile and the current "Garnet" version of Palm OS. The company last year introduced the Palm 680 with minor improvements to the aging operating system, which were intended to make it more friendly to consumers. By contrast, Palm pitches Treos running Windows Mobile largely to businesses, and new devices running both are due before the end of the year.
