Hi i am at a point at work where I can finally ditch the Dell and order a Mac. However due to budget constrains, I would like to hear some recommendations. The applications i would be running typically are: 1. Motion 2. Powerpoint 3. Flash 4. Final Cut Express or iMovie 5. Photoshop 6. Illustrator 7. Fireworks 8. iDVD 9. iPhoto At the lowest end- should I settle for an iMac? Will that help- especially if I am running motion? Thank you.
