I'm thinking about upgrading to a new iMac every year, similar to how some people get a new iPhone each year. My idea in doing this is to always have the best iMac available, and I'm thinking that after several years of buying, and selling my old iMacs, that it may make financial sense? If I could sell a one year old iMac every year for a good return, and apply the money towards a new one, as opposed to waiting 4-5 years when the iMac is very outdated, and taking a much larger hit on my return, possibly so much so that it is only worth several hundred dollars. I'm curious to hear if anyone else is doing this and what you think of the idea. Thanks.
