In a world first, we've managed to get our hands on a review unit of Sony's stunningly thin ultraportable. Most surprisingly, it sports the newest Atom chip from Intel - the Z550 2.0GHz and GMA 500 graphics.

So, the last big name has fallen. HP gave out in April 2008, and both Dell and Toshiba's resistance crumbled by the autumn. But it's taken Sony until the middle of 2009 to produce what it confesses to be a netbook, the VAIO Mini W Series.

An HD screen, Blu-ray drive, TV tuner and competitive price result in an excellent-value entertainment laptop.

A stunning piece of design matched with excellent battery life, but with an Atom inside the price is surely too high

Asus' new Eee PC 1004dn steps up in style and features, boasting a DVD-writer, expresscard slot and scrabble-tile keyboard

Sony’s Z-Series is an ultraportable to aspire to, even if there are a couple of areas where it could improve.

It’s gorgeous, but it can’t match Sony’s own Z-Series for sheer ultraportable excellence.

The design is impeccable, the build superb and the screen extraordinary, but the price is a huge barrier. We ponder the icon that is the Macbook Pro 17in

Sleek and professional, the Hp Mini 5101 is another attractively pitched netbook that can't shake its very poor battery life. When will manufactuers learn that battery life is all-important to netbook success?

Not quite the consumer/business crossover it aims to be, but there’s a lot to like in this clever mix of old-style business laptop and feature-packed modern machine

Superb speakers, a whopping 640GB of storage and decent core components make this a solid choice

A stunning piece of design to rival any Apple offering, and the price is surprisingly reasonable
