Ok, now to defend myself. First and foremost, I don't buy the Ferrari analogy. Nobody here fits into the category of old people who have spent their entire lives working and now want to have some fun before leaving this world for the next.
Regarding my old comments... Unlike others, I do in fact need the extra power of a MBP/PB. I do a lot of web design and Photoshop work and my 1024x800 iBook G4 has been absolutely killer. I made a big mistake and I will never repeat it. Other reasons why I will only buy pro hardware from now on include better resale value and "future proofness".
EDIT:
I completely disagree. Have you tried browsing today's internet using a G3? It is very painful, especially when using tabs or looking at websites that rely heavily on Flash, Windows Media DRM ****, etc. Oh, and take a look at Vista's or Leopard's system specs. Your "G3 processor (or a Pentium III)" will NOT do just fine, even if all you want to do is check your email and chat. You are not in fact getting that much extra horsepower when you buy a MB. The MB is pretty standard when it comes to modern computers.
EDIT 2 : One more thing. Gaming is a very good reason to buy a MBP. If you are into computer games, dedicated graphics is a must. I am not criticizing people who buy MBPs for this reason. I am criticizing people who buy MBPs just for "web browsing, iTunes, and Word processing."
That doesn't make too much sense. First off you don't need a MacBook Pro for webdesign so don't pull that one i use a macbook for that and it works well. Second, obviously they're not idiots if they can afford one of these machines.
Third, It's they're money, My Dad bought an XPS why, it's not because he plays games or does anything demanding really but he bought it because he likes it. and that ferrari analogy works fine it's the same thing.
