Sony FW31ZJ review


With a large, sharp 16.4in screen the Vaio FW is perfect for playing movies. But can it do much else?

Aside from a remarkable screen that’s great for movies, this is only an average performer

Sony Vaio VGN-FW31Z/J


Massive memory makes it a good machine for the likes of me (no expert). It is practically intuitive to use, it knows much more than me! It is a lightweight machine and is fairly portable for the size. The graphics etc are great for me and it looks good.

Good desktop portable. Fast performing 2.66 GHz intel core 2 duo processor. 4 GB RAM. DVD & BluRay recordable multi-drive. Capacious 500GB hard drive storage.

1.75 hour battery life at 80% charge (80% charge prolongs battery life). Memory hogging Windows Vista 64 bit bloatware.
