I’m writing this review of the Sony Vaio Duo on a Lenovo Yoga 13. It’s not a good start for the Vaio is it. The fact is though the Sony Vaio Duo is a really useful Ultrabook convertible and it has surprised me.

Sliders. They are in many respect a compromise. The space left for a keyboard is cramped and the hinge mechanism is complex leading to worries about longevity. In the past, I confess, sliders have always appeared to me as the show-off devices that don’t really deliver. I’ve changed my mind though because Sony have added a component to this slider which makes it the best I’ve tested so far. A Digitizer.
