Sony has made good on its recent promise to launch touchscreen editions of its Vaio all-in-one PC.

Sony's Vaio L: the touchscreen version comes in two flavours

The Vaio VPC-L11M1E/S and VPC-L11S1E/S both run the upcoming 64-bit version of Windows 7 and feature Intel Core 2 Duo processors inside.

But while the L11M1E/S makes do with the 2.93GHz E7500 version of the chip, the L11S1E/S has the 3GHz E8400.

Other than processing power, the only other key differences between the two 24in, 1920 x 1080 PCs are the L11S1E/S’ added benefit of a Blu-ray Disc combo drive – the L11M1E/S has a DVD rewriter – and DVB-T tuner.

Inside both models you’ll find 4GB of DDR 2 memory and a 500GB, 7200rpm HDD. Nvidia’s GeForce G210M graphics processor is also used by both the L11M1E/S and the L11S1E/S.

The duo’s other treats include HDMI connectivity, 802.11n Wi-Fi, Bluetooth, a webcam and integrated speakers which wirelessly connect to an additional digital amplifier.

Both Vaio touchscreen PCs will be available from 22 October – the Windows 7 launch date. Prices for the pair haven’t been released yet. ®
