Realistic ReviewIt's probably a waste of my time and effort, but I have a 1.33GHz 15" Powerbook and an Acer 1712SMi (3GHz), and I feel I can add some rational thought and comparisons here with regard to some of the points raised by David.
First, I really enjoy using both machines, and they can each do things that the other can't. Both are quality builds, and neither has given me any trouble. I use both for video production and other tasks down to surfing. I use the Acer on my desk at work each day.
Frankly, I don't understand the "It has to be one or the other" mentality that's so common, especially with Mac proponents.
Noise - The Powerbook is definitely quiet. I'm not comparing it to a Centrino, but even considering it in a vacuum, it get points on that - it is quiet. We used to have a desktop PC in the bedroom (always on), and now we keep my Ti Powerbook there - virtually silent; Always on, hooked up to a big external monitor and full size keyboard, it makes a great desktop. My wife loves it.
Heat - The back left bottom of the case gets hot (not warm, hot). I use it on my lap in the living room every evening and it gets uncomfortably hot, even just web surfing. It's vented on the back. I do like that part of the design; the bottom is just a flat surface; no vents, no fans. I'm not a gamer, but it would clearly be silly to believe that an hour and a half of play would only make any Powerbook just "warm."
Display - It could be a bit higher res and the brightness and contrast is nothing to write home about, but is "good" - not great, not excellent, but good.
Speed - The Acer and Powerbook were almost the same price, so in that regard, I think it's "fair" to compare their performance. I use a few applications in common. After Effects is one that has always been Mac-centric. The comparison with After Effects 6.5: the Acer kicks the living crap out of the Powerbook. The difference is about what you'd expect if you were given no more information "We're going to compare a 1.33GHz machine to a 3GHz machine. It's more than twice as fast. The subjective feel of the difference in most apps (including AE) is not that great. That might be one of the reasons that Mac users so routinely inflate the relative performance.
Now, the Powerbook is pretty, sleek, and stylish. It has a certain fitness in usabilty to it. It's pretty okay in terms of its weight and certainly has a place in my life - I'm not giving it up. OSX is largely enjoyable - and I also find XP to be a joy on a stable machine like the Acer.
I think its clear that David is just a kid - doesn't mean he'll grow out of the attitude though.
