Right now, I'm torn between a macbook and a macbook pro. I have a powerbook g4 and it's built extremely rigid. I was wondering if the macbook's physical construction is as rigid as the AL PB's. The reason I ask is that I haven't used or touched a macbook. My previous laptop was a dell inspiron and its constuction was soooo flimsy it was ridiculous. I could bend it back and forth and I don't want that to happen with another plastic laptop. Please let me know!!
