And the answer is....
First off, for all the people that answered the question I was asking, thank you for your help and taking the time to read the actual question.
Q1. What did you decide on in the end?
A1. I chose the G-tech 320GB external hard drive with quad interface and am absolutely loving it. It works wonderfully, has no fan (self cooling) looks great and was beyond simple to set up.
Q2. What was the mess up and who caused it?
A2. The mess up was by Apple Care. I want to first say how well the supervisor handled the situation and to Apple's credit worked diligently to rectify a pretty poor showing, one that I will note is bound to happen in any company. Now, the problem. I sent my powerbook to apple care because of an awful sound it was making whenever I lifted it; the noise was literally metal on metal grinding.
After waiting for the powerbook for over 21 days, it was finally sent back to me. The motherboard, logicboard, and thermal plate (no idea what that is?) were all replaced. I began to load all my data back on, but about halfway through it became immediately apparent there was a problem. I was typing an email while loading the data and noticed that it literally took about 10 - 15 seconds for each letter to appear as I typed. Then everything froze up and I got spinning beach balls galore. I shut down, which took about 30 minutes to do since since whatever the problem was, was having this major slowdown effect. Upon restarting the computer, it took over 6 minutes for it to start up. After about 20 minutes of regular internet and email use, beach balls galore and again very slow start up.
I called apple care and I gave a very detailed description to the person taking the apple care request. I made sure that they
removed the loud grinding noise as the complaint and only listed the current problem. I received my apple care box for shipping and checked the order slip. Yep, you guessed it, what do you think the problem was that they had listed? loud grinding noise. I called apple care again and told the person the order was wrong and asked them to read back to me the corrected version I gave for the second time. In fact, I did this before I would even send the computer out for repair so as to prevent any confusion and even then waited a day before sending.
After checking its status online, I noticed there had been a stop order placed on the powerbook and a request for me to call. I did and the customer rep. said they were unable to replicate the problem. I asked if they had left it on for about 30 minutes before it slowed down... "slow down, what do you mean slow down? It is a grinding noise you were asking about!":

I mean come on. I told her no it is not, I again articulated the problem. They went back to work and you honestly wont' believe this, but I get a call from the tech working on it in texas who tells me he doesn't understand what sound I am referring to and wants me to describe it. At that point I had had it and asked for a supervisor.
Long story, somewhat short, I eventually got the powerbook back after close to two months. I rarely ask for things above what I think reasonable to expect based upon what I have paid, but honestly, this one deserved a big "I'm sorry." Oh, they also threw in a couple different very cool Apple t-shirts. It was a bad mess up, but was resolved eventually by a proactive and dedicated supervisor. That's the story in its entirety, well almost the whole story, I left out the whole power failure that hit apple's call center in Canada and disconnected me and lost all records of my third attempt to explain there was no noise problem.
