I am going to be purchasing Adobe Creative Suite 4 Design Premium (Photoshop, Acrobat, Flash, Dreamweaver, etc) shortly but want to make sure I have enough horsepower to be able to run it. Ideally, I'd like to have this on my laptop so the program can be portable, but at the same time I don't want to be hauling around 10 pounds of equipment with me. So I'm looking at the MacBook pro 13" and am wondering if the 2.53 GHz, 4 GB of memory, and the 250 GB drive is enough power to be able to run CS4. I like the idea of a 13" as it's lighter to carry around, but when I look at the 15" version it looks like I can get a bit more processor and drive space, but more importantly it looks like the graphics are a bit better as well. I'm just trying to ascertain whether the graphics card on the 13" version will be an inhibiting factor to using CS4 Design Premium. Any thoughts are appreciated.
