Hi I am looking to switch from a PC to mac. This is my first post.I have been reading posts on this forum for a while to decide on which mac to choose. I want to get an iMac for graphic designing (photoshop). my budget is just above £500.(1,008.50 USD) 1)should i get the new imac - will the glossy screen be an issue for photoshop or too distracting? 2)or should i get I get a 20" old mac because it is cheaper and works fine (have the prices of the new ones been reduced)? 3)If buying an old mac should i buy a refurb and will they come with ilfe08. 4) Will a refurb of the old mac come with leopard if I wait for it to be released later in the year. I will be buying the mac in november (thanksgiving) in Newyork, when I am on holiday from london. Thanks for all your help in advance.
