PC Pro has a review of the Asus U2E-1P014E and they write “All in all, the U2E is an attractive, well-built laptop - but it lacks the wow-factor of Sony’s rival ultraportable. Sure, the U2E weighs less than the VGN-TZ31 but, crucially, it just doesn’t provide the battery life to match. And while it’s noticeably cheaper than the Sony at £938, it still holds a significant premium over more commonly sized laptops. Unless you need to use every feature - including the optical drive - and look good doing it, then one of Asus’s own Eee PCs would do the same job for a quarter of the price.”
