I need to buy a new computer for my office and am unwilling to learn everything about computers to pick one. I don't game on it, I do use iTunes and would like DVD/CD and need several USB ports. My 2002 Gateway is slowing and I am informed that it has "swollen capacitors," indicating future trouble. I have been steered toward Gateway DX4300-15E but can't find anyone actually selling it. Also, ACER AX3950-U2042. Can anybody suggest a computer or how to go about choosing a computer??
