I am a designer by trade and use photoshop almost exclusively. I currently work on a g5 PowerPC 1.6 and am looking at a used MacBook Pro 2.6. I'm looking for the mobility of a laptop and more speed. Also price is important which would explain the choice for about $500 used. Will the MacBook Pro be the laptop I'm looking for or are there any other suggestions? Thanks for your time... New here.
