Battery Life to Weight Ratio
Here, we are interested to find out the 'mobility' of the Dell XPS M2010. We are sure that most readers would instantly give it the thumbs down for this criteria on learning about its 8kg weight and they would be correct in their instinctive assessment. However, we are interested in the raw scores to find out how does it compare to previous notebooks that we have tested.
In order to normalize all relevant factors between notebooks of disparate sizes and weights, we used a simple measure of ratio between the battery life, volume and weight of the notebook by dividing the battery life of the notebook (as derived with MobileMark) with the product of its mass and volume. The Dell XPS M2010 scored the lowest ever from our list of more than twenty notebooks and considering the margin between it and the second lowest, it is probably very difficult to find another comparable example. This is perhaps the worst-ever portability index we've ever come across and it could very well be the only one - for now. The XPS M2010 is a desktop in everything but name and it would probably be fairer to compare it against a SFF.
Power Consumption
After we measured the overall power consumption of the Dell XPS M2010, it turned out that Dell has kept the power demands of this notebook relatively in check as it did much better compared to other desktop replacements like Dell's own Inspiron 9300. Pitted against other portable business notebooks like the NEC Versa S5200, the XPS M2010 consumed marginally more but that was to be expected. Overall, for its hardware specifications, the Dell XPS M2010 has fared surprisingly decent in this department.
