Two different approaches to ultra-portable PC: £135 Acer C7 Chromebook & £1,200 Sony Vaio Duo 11

Sony's Vaio Duo 11in hybrid laptop was unveiled nearly a year ago at IFA in Germany and can now be purchased with a 20 per cent discount from online retailer Expansys for £1,200. This is an exceptional piece of kit combining a full HD touchscreen panel with an 11.6in diagonal plus OptContrast and Mobile bravia Engine 2 technologies and some cracking components like an Intel Core i7-3517U clocked at 1.9GHz with two cores, 3MB of cache and based on the Ivy Bridge architecture (which means that it comes with an Intel HD Graphics 4000).

The rest of the feature list reads as follows; a slide-away keyboard, two USB 3.0 port, GPS, 8GB of RAM, a 256GB SSD, Windows 8 Professional, Bluetooth 4.0, Wi-Fi, Gigabit Ethernet, VGA and HDMI out, a card reader, two speakers with xLoud technology two full HD webcam powered by Exmor for PC, NFC (plus a number of other sensors), a digitizing stylus and a weight of around 1,300g. We're thrilled by that laptop but not by the fact that it uses a sliding mechanism and that it doesn't come with a touchpad.

At the other end of the spectrum is the Acer C7 Chromebook from Bargain Crazy which costs a mere £135 once you use the voucher code WTEN at checkout to grab a 10 per cent discount. That is a cracking price given that we sourced the C7 last month for £179 at Tesco Direct.

Note that this is a refurbished computer that comes with a year's warranty and that its price excludes delivery). This is a Chrome-based OS, which means that it omits the cost of a license (Windows 8 Professional probably costs as much as the Chromebook by itself).

When it comes to the specification, it is similar to a bog standard netbook with some cosmetic differences. There's a dual-core Intel Celeron 847 processor clocked at 1.1GHz, 2GB of RAM, a 320GB hard disk drive, an 11.6in Acer CineCrystal LED display with a 1,366 x 768 pixel resolution, an Intel HD Graphics GPU, an integrated HD webcam, Wi-Fi, three USB ports, HDMI out, nearly four hours battery life and a card reader.
