I have a friend who is about to make the move to Mac. He wanted some recommendations as to the 21.5 iMac. He does not have the space for the 27 inch. Since his primary use will be word processing for work and web surfing. I suggested the 2.7GHz Quad Intel Core i5 processor with Pages as a complete package. As for memory, I told him to stay with the 4GB and if he needed more he could save by adding it on through the secondary market. Are there any other suggestions as to what else he should add on and/or install?
