Envy 14 Spectre depth vs DM4 depth
Elsewhere, the lightweight, thin design is intended to be another compelling factor in the ultrabook's favour.
Here, too, there was less difference between the two machines than expected: the Spectre is the thinner of the pair, though not by much.
At its thinnest point, the DM4 is almost exactly as thin as the Spectre. Officially, the Spectre measures 20.06mm across the entire chassis whereas the thinnest point on the DM4 Beats Edition was 24mm and the fattest point was 32.3mm. For comparison, HP lists the Spectre's weight as "starting at" 1.8kg and the DM4 as around 1.96kg. Likewise, the company lists the battery life of the Spectre as up to 9.5 hours and the DM4 up to seven hours.
