Sony's carbon-fibre VAIO Z is the lightest, most powerful and most versatile ultraportable available. With highlights like an optional Full HD screen and up to a 512GB SSD, and with its optional dock offering dedicated graphics and Blu-ray playback, its rivals don't even come close – especially since battery life is also good. As a package, it has no competitors, though for many users the Z won't justify its extra cost over either its S-series cousin or other rivals like the MacBook Air. However, while it's not without its faults, if you can afford it this is a stunning machine

Cons

1- No built-in optical disk.
2- No built-in switchable discrete graphics.
3- Small track pad.
4- Poor speakers volume.
5- Dose not look as premium as last year's Z
6- The extraordinary cylindrical hinge design is gone. 
7- Way overpriced.
8- Not yet a uni-body design.
8- Power Media Dock.
9- Only one built-in USB 2 port

Pros

1- Very powerful - full-power processor!!
2- Thin, and super-light.
3- Long battery life.
4- Extended battery sheet option.
5- SDD and super-fast booting.
6- Light Peak implementation.
