Looking to purchase a laptop needed for web design. I will not be coding, but using a lot of Adobe products (indesign, photoshop, etc) and figured a macbook pro with retina display would be my best bet. Is now a good time to purchase? By good time I mean in regards to the latest model being released. It seems that the macbook pro with retina is relatively new (considering the latest upgrade); however, I've been reading that the macbook pro will get a refresh this June? Any idea if that's true and if so would it be worth waiting. Lastly, I think the 13.3 will suffice but is it worth the extra $600 for the 15?
