Ok Apple Fans, Im thinking about making the switch...

Ive decided that I definitely want to buy an iBook. I'm looking to buy the little 12" one so i can have something small for class, traveling or carrying around without ac adapters.

My question.....do I get it before the Intel switchover or should I wait until after Apple makes the change to Intel based processors? Ive read many things so far that have taken both sides and I like the ability that you should be able to run a windows program at full speed on your Intel based mac (without virtual pc), but I don't want to end up with an overpriced pile of junk when basically I can just buy a PC laptop for much cheaper and it does the same thing.

So, help me weigh out the positives and negatives for both sides so I can make my decision in the next couple of months.
