For all you computer nerds, this video is really something. http://www.hitachigst.com/hdd/research/recording_head/pr/PerpendicularAnimation.html I found this video cause New Egg is selling a 320 gb SATA drive for $85 w/ no shipping. That's a good deal. But the video is great. Anybody ever heard of this technology? It sounds like it could be a breakthrough. What are the pros and cons?
