Ok here is my predicament. I currently have a 15" powerbook 1.5GHZ. It is in ok shape. However, lately I have found my self wanting more power and have lusted for the new aluminum imac. I have not had a desktop in 4 years but the imac is getting great reviews and it looks oh so sleek. Anyway, I am trying to decide if I should by a 20" imac or save for a new mac book pro. I do take my laptop a lot of places and I love surfing the web on my couch or in bed. But a new macbook pro is really expensive. To make things more enticing, my school is offering a free 1gb upgrade to 2gb with the purchase of a new imac on top of the $50 discount. I am curious to what other people would do if they were making this choice so please comment! What are the pros and cons for each system? Thanks.
