I'm trying to decide whether or not to go with a 15" 1.25 GHz powerbook or the 17" 1.33 GHz powerbook. I'm looking at the stock setup in both so essentially the machines are identical except for the clock speed. Originally I wanted a 15" but the store I was planning on buying from says they are on back order and delivery date with the superdrive is anyone's guess. Furthermore the 17" at this place is in stock and the same price as a 15" at other stores in town. So given the choice between a 15" and 17" at the same price what is the better choice. I'm a student and I plan on taking the PB to the lab on a daily basis. Any thoughts or suggestions are welcome.
