We already mentioned several other Lenovo machines that were announced in the last 24 hours at CES 2013 and today there are a couple more to add to the list.

ThinkPad Helix – Lenovo calls this ultrabook a premium convertible device that uses what they are calling a rip and flip design. This design allows the user to put the device to use in four different configurations ultrabook; Stand mode; Tablet mode and a base mode where it remains attached to the keyboard dock in tablet mode to provide access to the extra ports on the dock unit. They say it will get 10 hours of battery life, comes with a precision pen, full sized keyboard and five button click pad. It has am 11.6 inch 1080p HD IPS screen which they indicate gives good visuals anywhere. The device also has Near Field Communications (NFC) built in.

IdeaPad Yoga 11S – this one is labeled a mini-ultrabook and is actually an upgrade on the previously released Yoga we have already seen in stores and in commercials. This one comes with a low power option with the 3rd generation Intel Core i5 processor and of course Windows 8. It has an 11.6 inch HD IPS display with 10 finger multi-touch support and includes features previously available on the Yoga 13 such as Motion Control which uses the devices webcam to move through documents, pictures, etc. and Lenovo Transition which automatically opens up applications in full screen when using the device in tent, stand or tablet mode.
