For the original German review, see here.

HP's German shop presently lists three versions of the slim all-around laptop. We are testing the lowest priced model, Envy 15-j011sg at approximately 800 Euros (~$1101). In addition to the components mentioned above, it also features a large 1000 GB HDD, and a total of 12 GB of DDR3 working memory (4096 + 8192 MB). An operating system is naturally installed. Like most contenders, HP relies on the 64-bit version of Windows 8. However, an optical drive is not available.

The buyer can get the Envy 15-j017sg for almost 50 Euros (~$69) more. It not only has 16 GB working memory, but also features a stronger graphics unit. Nvidia's GeForce GT 750M mid-range champion calculates much faster than the GT 740M. However, it also needs a larger power supply (120 vs. 90 Watts). The other components should be identical.

If the buyer's mind is dead set on a quad-core processor, the 1000 Euro (~$1377) Envy 15-j013sg will be the right device. It sports a Core i7-4702MQ rather than a Core i5-4200M (both 37 Watt TDP). There are no other differences according to the spec sheet.
