Uh, yeah lol. Here's an article about 160gb Fujitsu hard-drives in laptops. Instead of writing data horozontially, these drives write data vertically fitting more on a drive. It's pretty neat, but it's probably not going to go mainstream for a while.
Oh... Hitachi should've kept it for themselves, as I never hear about Hitachi these days... it's all about Western Digital Raptors and Seagate 750GB Barracudas now.
