It's like what you learned with the i386 was much more inline with a trade school level of learning vs the more theoretical learning of a university. you learned the down and dirty and was immediately able to do something with it. it didn't teach you the hows & whys and blah blah. it's that 30,000' view vs 10'000' view vs down in the trenches view. sometimes you need all of the views, but some tasks don't always need the 30,000' theoretical lesson
