I am trying to quit smoking. I am down to half a pack or less a day, started this last week. Consider that I used to smoke a pack and a half a day. The computer technician has also greatly reduced how much he smokes a day. Then again, he's been fighting a nasty cold the last couple of weeks so needless to say he has not had much of a desire to smoke. The computer technician said that if I am able to quit completely or GREATLY reduce how much I smoke that he would buy me the newest version of the iMac. Yes this is a good incentive for me to quit, but at the same time I am happy with my current iMac, which is about two years old. The new iMacs are nice, with a bigger screen compared to what I currently have but I do not like the gray and blac design. Other than that there are no differences between the new iMac and what I have, at least in my opinion. Then again, I'm not the Mac expert my other half the computer technician is.
