I am new to macs and have just bought my first one (used Imac 1.8, 17"). It is in excellent shape and has many extra programs installed and has made me a true Mac convert. I did manage to sell my old computer and got more than I thought that I could and now realize that if I took that money and could recoup close to what I paid for this unit I could pay cash for a new Mac MINI base model. I am in a quandary as this Imac has given me no indications of any problems, but it is a first generation model (5 years old) and you never know. Would appreciate any opinions.
