Ok. Long story short I am replacing my Macbook Pro Unibody 15" with either a 13" Macbook Pro or 13" Macbook Air, I am even considering the 17" Macbook Pro. I currently have a 20" Imac that I use for most of my design work, now that my UMB 15" is dead (May she rest in peace!). While I would love to have the 17" for working on web design projects, I would love to have the portability that I never got with the UMP 15". Can a new MBA SSD 2.16 run CS4 Design Premium with out many issues? I would mostly be using dreamweaver and photoshop if on the read or not at the office.
