I'm getting ready to buy now, and think I will eventually have a MB or MBP for mobility and an iMac for home. The order in which I get these is flexible. I was thinking of getting one in the next few weeks and then the other after Santa Rosa came out. I was leaning toward getting a MB now and an iMac (or future small tower) later. However, is the Santa Rosa chip set going to be primarily for laptops or for all systems? Any recommendations on which to get first?
