The flagship 13.3-inch Vaio Z which goes up for preorder in Japan, and it is based around  a second -generation high-speed SSD and an unspecified fifth-generation Core i7 processor, in an aluminum-carbon shell.

It's been three years since we've seen the flagship Z series.  This time it has a  'multiflip' mode that allows users to switch between a tablet slate, ole-fashioned laptop, as well as a viewing mode where the screen faces away from the laptop.

Because of the aluminium-carbon construction, the Z weighs 1.34kg and measures in at 16.8mm thick. Vaio said it will run for  15.5 hours which would make it the longest lasting laptop it's ever made.

This was managed by recomposing the battery inside the Z, shedding several layers inside the cell to improve capacity without impinging on weight or size. There's also a special power-saving display mode, where the screen projects its light in a narrower angle, which can apparently drop power consumption down by an incredible 40 percent when compared to typical LCD.

However it is not cheap it'll retail for around $1,600.

The VAIO Z Canvas will come in May. The keyboard detaches from the 12.1-inch 2,560 x 1,704 resolution display. It looks pretty much like an Ultrabook. There is a digitizer stylus alongside the device itself. Vaio said you can save a TB of data on it.
