Different answer for everyone, I understand. But I'm seeing the iMac lineup is slowly getting the i5, and a 27" screen. I'm no fan of the glossy surface (is there a matte film that could be used?), or limited expandability. But what I would be using it for might just make more sense. And cheaper. I'm doing a lot of Photoshop, essentially image generation via Wacom Cintiq tablet. No file sizing much over 75Mb, for example. Several layers, for sure. Often open apps like Illustrator, Firefox, Mail, etc. Cross functional workflow rarely gets more than those with an occasional Dreamweaver thrown in. So, if I bump up the ram, set up my external drive, what would be so different between this possibility and a midlevel Mac Pro? For my use, I'd love to hear some opinions. Thanks.
