Oh, how the times change! In August of last year we were talking up a 128GB SSD drive for Dell's XPS laptops like it was some kind of hotness -- and only $450! Now that same drive is a mere $200 upgrade, while a new 256GB SSD has been introduced to Dell's XPS M1330 and M1730 laptops for "only" $400. Sure, six months from now we're gonna be chatting up a slightly cheaper 512GB SSD and laughing at our January selves, but we just can't help ourselves and this pesky linear of progression of time we're so beholden to. Dell's also now offering a 7200RPM 500GB HDD as well, and plans to introduce both of these upgrades to additional laptops in the next few weeks.
