Unconventional choice: Panasonic Let's Note.
Sadly JDM exclusive and has soldered RAM, but the latest models come with a 3:2 display, decent I/O (e.g. RJ45, full sized SD card reader, even VGA (!)), magnesium alloy chassis and a removable battery in a sub 1.1 kg package. Can't speak for the quality of the trackpad or keyboard though.
