So I'm going to switch to Mac. I've worked on various machines designing brochures/posters/websites for my university and the more and more I use them the more and more I love them and OSeXy. Here's my dilemma. Not much money, and I need: - Something with enough punch to work with lots of large image files (Photoshop et al.) - Something with a BIG display to have mulitple documents/images open (I do coding too) - Something quiet that runs cool as my current laptop sounds like a jet engine Basically it comes down to this: How much better is the G5 2Ghz in the 20" iMac compared to the G4 1.5Ghz in the 12" Powerbook? Would running intensive programs on the PB with dual monitors cause performance issues or make the machine run hot? Is the display in the PB anywhere near as nice as the display for the iMac? Any knowledge or opinions would be wonderful to hear. Hopefully I'll be joining the Mac world soon and it's great community!
