Sony VAIO VGN-TZ31MN/W notebook


With mini-notebooks like the Acer Aspire One and Eee PC 901 grabbing the headlines of late it's easy to forget that ultraportable notebooks you can carry around with you are nothing new. Sony, for instance, has made it a speciality of its range.

Sony joins the ultraportable contest with a simply gorgeous mini-laptop. Mattew Sparkes finds out if it has enough to compete with the MacBook Air and Lenovo X300.

Expert review by: Matthew Sparkes (



Up until recently, Sony had the high-end ultraportable market almost to itself - but that lack of competition didn't stop it achieving great things. The VAIO TZ21 we reviewed in January impressed us with its incredibly low weight and unprecedented...

This impressive ultraportable fills a narrow but handy niche in between the MacBook Air and Lenovo X300.
