HP has recently updated their Envy 15 with the latest in processors and graphics cards. This is a preliminary review that contains info on the processor and abilities of the new model. The Envy 15 can now be configured with an i5 (Dual core + hyperthreading) and i7 620m processors [It appears the i7 620m may have been removed from the configuration options. 1/21/09]. The significance of this primarily going to be found in increased battery life and less heat generated due to the i5 and i7 620m being manufactured on a more efficient core size (32 nm). Battery life is expected to increase from 2.25-2.75 hours to around 2.75-3.5, or maybe even more if HP enables the built in switchable graphics on the new processors (if HP allows switchable graphics, the battery life could reach over 4 hours without the slice and 10 hours with the slice). » Read more: HP Envy 15 with i5 (Preliminary) Review
