I have had a 17'' Core Duo iMac for about 6 months, I have been very pleased with it. I maxed it out with a 250 GB HD and 2GB RAM. Sometimes however, I am on the go and I just wish that I had a computer with me. I knew from about a month and a half after my iMac purchase, that I wanted laptop instead, but I had never brought up interest to do so. Now that the C2D Macbooks are out, this has brought up that interest once again. Should I sell my iMac to then purchase a Macbook? How much do you think is a reasonable price to sell my 17'' CD iMac for? Has there been any problems with the C2D Macbooks as of yet?
