Lenovo has announced four new convertible tablet/notebook hybrids designed for Windows 8 and Windows RT: the IdeaPad Yoga 13 Ultrabook (S$1,899, mid-Nov), Yoga 11 (S$1,199, early-Dec), ThinkPad Twist S230u (S$1,699, available today), and Tablet 2 (S$899, mid-Dec).
Both IdeaPads can be pre-ordered now.

The theme of the launch event at the National Library Building in Singapore was “Flip, Flex, Bend, Twist”, which describes the various ways in which you can manipulate the new convertible tablets.
I played with the devices on display and found them responsive to the touch of the fingers.
I like the hinge design of the Yoga which allows the screen to be flipped 360 degrees onto itself to convert the Ultrabook into a flat tablet (and as a free-standing display enroute).
The 16.9mm thin Yoga 13 also felt light at only 1.54kg.
When the screen is flipped more than 180 degrees, the keyboard and trackpad is disabled to prevent accidental activation of these while holding the Yoga.
Below is a summary of the four new devices. All are Wi-Fi capable but only the Tablet 2 has an option for 3G.
