ITreviewed posted a review on the Dell Inspiron Mini 12

Available in black only, the Mini 12 is more than capable of handling the basic computing tasks it was designed for. However, thanks to Intel's wretched graphics chipset and poor driver support, the video playback - both streaming Internet video and files stored on the hard drive - brings the machine to a crippling halt. To add insult to injury, the Mini 12 boats an operating time of under 3 hours from the 3-cell 2200AHr battery, which is pathetic. There is the option of using a 6-cell battery to extend this to a more respectable duration, but this will add to the weight and cost. What with a pitiable battery life and lack of integrated 3G, Dell has failed to encapsulate what a netbook is all about.
