It almost hurts me to type this, but I guess you have to start somewhere. I was a complete noob when I bought my MacBook Pro - it is my first Apple product and laptop in general. I stumbled upon my shipping papers earlier which got me thinking about when I purchased it and knew nothing about hardware. While I still consider myself a noob, I know way more now then I did back then, mostly thanks to these forums. : ) Anyway, I noticed that I basically paid around $100 (if my calculations are correct) to go from a 5400 RPM 250GB Hard Drive on the low-end model to a 5400 RPM 500GB Hard Drive. Yeaaaahhh. Did anyone do this or anything similar (in terms of stupidity) regarding any parts or anything MacBook Pro related from any retail or site?
