Computer parts price graphs for trend analysis: Feedback?

Hi, I just put up a website that I started as a project for my father, just to kind of get a feel for the market and recommend a platform for him based on general price and performance. I also had to gather some data cos a lot of hardware had been released in a relatively short amount of time, and didn't want to buy some decent hardware right before a bunch of price cuts would shave $200 off the total system cost.

Anyway, I was wondering if any fellow hardware junkies wouldn't mind checking out the website and offering me some feedback. If anyone wants to contribute to the market analysis section, it's open.

Let me know what you think. Is it useful? Should I add some more watchlists to get a feel for what everyone else is buying? Any features I should add?
