There are three models -- top of the range is the VPCF11Z1E/BI (those letters must mean something to someone at Sony HQ) with a quad-core Intel Core i7-720QM processor running at 1.6GHz and 8GB -- yes, 8 -- of memory. There's a Blu-ray writer and an Nvidia GeForce GT 330M graphics chip with 1GB of its own memory -- impressive specs for a laptop.
The screen is designed to show off the laptop's HD capabilities -- it's a 16.4-inch behemoth with a Full HD resolution of 1,920x1,080 pixels. A light sensor adjusts the backlight to match the brightness of the room, and there's a 'display off' button, in case you're inclined to use this as a hi-fi and don't want to stare at your Windows desktop.
A large screen means a large keyboard, and this 'laptop' is so large there's room for a number pad on the right, as on a normal desktop keyboard. At 3.2kg, it's probably best to think of the machine more as a desktop you can fold up and put away in a drawer, rather than a portable computer.
802.11n Wi-Fi and Bluetooth are built-in, as you might expect for something at this end of the market, along with a 500GB hard drive. Sony claims a 3-hour battery life.
It will pop into shops from 18 January -- no pricing has been announced, but we'd be surprised if it comes in well over £2,000.
If this ends up being too expensive for your tastes, there are two other models coming along at the same time. The VPCF11S1E/B has less memory and a Blu-ray reader rather than the writer, and the VPCF11M1E/H has a dual-core chip and smaller memory still.
All the models ship with Windows 7 64-bit and a bunch of Sony software packages designed to organise movies and pictures.
