More delays are coming today, as Everex's highly anticipated ultramobile CloudBook PC launch will have to wait a month or so, because of some last-minute changes to its Linux-based software. CloudBook was supposed to be available from Wal-Mart Inc. stores and the Walmart.com Web site today. Unfortunately in an e-mail, Everex's director of marketing, Paul Kim, said that "a couple of last-minute software tweaks" prevented the CloudBook, a competitor to rival Taiwanese ASUSTeK Computer's successful Eee PC, from reaching stores just three weeks after its debut at the Consumer Electronics Show. The $399 computer runs gOS, a flavor of Linux based on the popular Ubuntu distribution but with a reworked user interface aimed at smaller screens like CloudBook's 7-inch display. The upcoming Chinese New Year holidays are also delaying the CloudBook's rollout.
