9. Toshiba NB550D - £291
For a machine so clearly geared towards portable use, all-day battery life is essential and the Toshiba delivers in spades. Running for 10 hours during constant, demanding use, you can easily work for a full day away from the mains.
The whole machine feels exceptionally well built and this quality extends to the user interface, with the keyboard proving well made and great to use. Even the touchpad manages to impress, with its large dimensions providing easy accessibility.
While the screen's 10.1-inch design is found on most netbooks and is a bit too small to use as your main machine, it's stunningly bright and vibrant. The NB550D is perfect for keeping you entertained when on the move.
Audio performance is also excellent. Stereo speakers are built into the palm rest and deliver a powerful, warm and defined sound.
AMD's Fusion technology also provides ample performance for watching HD videos and even editing your photos on the move.
Finally, the extra features are great. There's Bluetooth 3.0, an HDMI port and free software includes tools for office use, internet security, video editing and data backup.
