HP refreshes the Pavilion dm4 with a subwoofer, unveils requisite Beats Edition

It's shaping up to be a wild day for HP: in addition to revamping its Envy laptops and announcing its first Ultrabook, the outfit went and refreshed the mid-range Pavilion dm4. While it has the same metal-heavy design that bowled us over in our review, it trades Altec Lansing audio for Beats and gains a subwoofer. Otherwise, its entry-level specs -- a Core i3 CPU, 6GB of RAM and a 640GB 5,400RPM hard drive -- closely match the starting config available today.

And, while the company was at it, HP also announced a red-and-black-spangled Beats Edition. An inevitable move, if you ask us: HP has been pushing its partnership with Dr. Dre so heavily that it went so far as to redesign its Envy laptops with a prominent Beats dial. Then again, this is the first time HP's given the Beats special edition treatment to anything other than a top-shelf machine. In any case, you better be pretty sweet on that red backlit keyboard -- the gussied-up, Dre-approved version starts at $900 (headphones not included). Then again, at least you get beefier specs for the money: a Core i5 CPU, 8GB of RAM and a 750GB hard drive. If nine hundred bucks isn't what you had in mind, the classic dm4 starts at $630. Both will be available December 18th. If you're curious, find the full PR after the break, along with some rubbernecking hands-on shots below.
