Hi, I haven't come to start a huge war on what is best a PC or Mac - infact I am desperate to make the leap but I can't seem to justify the £1700 price tag of the MacPro which is the only single thing stopping me from making the leap. Apart from the base price, the cost of upgrading seems ridiculously overinflated - to go from a 1GB to 2GB set-up it's an extra £190! The same upgrade for a DELL would be under £50. Likewise to jump up to a 500GB hard drive your talking an extra £210 to Apple, but the same for a DELL is under £150. Is there a reason for this? PS: I am a graphic designer who runs CS3 all day every day pretty intensively and often working with large print files - could I get away with an iMac? Is it only video people who need this expensive computer?
