Yeah, but it's always easy to do this kind of number crunching assuming you know exactly when you will sell the stock. Of course, that's never the case in real life. Imagine the time you would spend worrying about your investment and analyzing when it will go out or go down or when to exit, etc. If you convert that into money say $20/hr, is it still worth it to invest as suppose to buy the PowerBook? Better yet compare it to the efficiency you have gained by having a PowerBook, or if you are a hacker, how much more you'd have learned by having a computer then. How would you even go about quantifying that?
