Libretto exited the common consciousness almost as quickly as it entered it while the Folio 100 was bad enough to get its major UK retailer to discontinue it? Toshiba promised it'd have a family of tablets for us by the end of 2011's first quarter and the plan apparently hasn't changed. DigiTimes is reporting today that three new Toshiba slates are set for their debut at CES in a month's time, two of them equipped with 10.1-inch screens and a third sized at 11.6 inches. Microsoft's Windows 7 and Google's Chrome OS and Android will each be responsible for providing the operating environment on one of these new tablets, indicating that Toshiba -- much like the rest of the world -- has yet to make up its mind about what the best tablet OS out there is. We should know more in just a few short weeks.
