Hello. I was wondering, would it be worth the cost to get a 24" 2.4ghz imac? I currently have a mbp 2.16ghz 2gb ram (one of which i would move to the imac to total 2gb in teh imac). when using imaging applications such as photoshop, capture nx, and aperture (w/ huge raw files), would i be able to expect significant improvements in performance with the imac over the mbp? or would it be minimal? should i just save the money and stick it out with my mbp? Thank you in advance.
