I have a 3 year old Powerbook. It's been great. My first mac, and it's still going strong. It is, however, power pc, and I'd really like to have something newer. I've been eyeing the new iMacs, especially since they are cheaper than the MacBook Pros. I'm just a little wary - when I bought my laptop, six months later the intel chip notebooks came out. I realize that's the way things work, but I just wanted to see if anyone had any strong opinions one way or the other. Is now a good time to get a new mac? I'm thinking of splurging on the big iMac...hopefully it will last me three years like this laptop.
