Shh... don't make too much racket while tweaking the website, else prospective buyers might actually notice that we're upgrading machines! Color us confused, but we can't figure out for the life of us why HP has taken that tactic of late. Within the past few weeks, we've seen not one, not two, but three of its Pavilion laptops get updated with nary a peep from HP itself. This go 'round, the dv4t is getting fitted with a LED-backlit display, Espresso Black and Moonlight White color options, integrated WWAN (Verizon or AT&T), a 500GB HDD and optional NVIDIA GeForce G 105M (512MB) graphics. There's also a Blu-ray option, integrated HDTV tuner and a 12-cell battery to choose from, but we'd only spring for those if money ain't a thang.
