I am perfectly happy to pay Apple a premium for their products, I think with as small as their maket share is, that has to be expected. However, I am willing to pay that premium for a top product. For example:
If I have to pay $4000 for a lap top vs $3000 and get all of the lastest and greatest hardware (which this PB has a lot of, but by no means all - note the 4200RPM Drive, and lack of a faster bus etc..), I am willing to do this.
I don't care about $1000 wintel crap, I have no intention to buy it, but if I'm gonna pay a lot, I want a lot. Apple tends to deliver this, and this is why they'll be around a long time.
