"The $150 Hisense Chromebook is a Walmart exclusive that lives up that inexpensive, nigh-disposable ethos Google seemed to be targeting when Chrome OS was first pitched. Low prices come at a cost though, usually in terms of build quality, performance, battery life or all three. And this little tyke isn't about to flip that script: it includes a meager display, an off-brand CPU, and a dull plastic body.
But the Hisense costs only $150 (that converts to £103, or AU$195) . That makes it one of the cheapest Chromebooks we've seen to date -- most models start at around $250..."
Pretty fair battery life - over 6 hours
