I'm looking for some buying/selling advice. I currently have a 17" Macbook Pro 2.16GHz Core Duo that I've been happy with since I've got it. I've used it as a desktop replacement and for design work. I also have a 1000H eeePC that I use to take notes at school. I was wondering if perhaps It might be a better idea to sell the 17" Macbook Pro and eee to get either a Macbook or 15" Macbook Pro. I'd like to not spend any money if possible. If I could only afford the new Macbook would it be a worthwhile upgrade performance wise against the 17" Core Duo? I know it's a bit like comparing apples to oranges. I don't need the 3d performance. I plan on using it for Lightroom, Photoshop and InDesign while hooked up to a monitor. I was also wondering if there's anyway to estimate the current value of my 17". Any thoughts? Thanks!
