Sony is keen to get in on the ultra-light laptop market, which seems to be a popular move these days. Apple, Samsung and Asus are all selling incredibly lightweight, but powerful, machines.
If you're looking for something with the portability of a netbook, but the power of a desktop, these are the machines for you. The problem is that Sony's new Vaio starts at around £2,000 and doesn't stop until it hits £2,700 for the top-spec model.
These are not computers that will be within everyone's reach but, for those who can afford one, the Vaio Z is likely to be an attractive proposition.
