ASUS just took the stage during its 2015 Consumer Electronics Show press conference where CEO Johnny Shih made several product announcements. Those products include the new Transformer Book Chi family of Windows tablet convertibles. The family is composed of the T100 Chi, the T300 Chi and the T90 Chi.

ASUS chairman Johnny Chih compared the high-end Transformer Book Chi device to the Apple MacBook Air and said it offers twice the speed and highlighted the device’s razor thin formfactor. It features a full-size keyboard and up to 8 hours of battery life. “The ASUS Transformer Book Chi is the ultimate dream machine,” Shih said.
