Here's my dilemma. My core 2 duo MBP is my primary machine which I use for audio and multimedia production. I don't like to take it anywhere but often find myself distraught that I don't have it with me. I've been drooling over a second machine (maybe the 13" MBP) to carry around with me and not worry as much. My question is, should I go ahead and get the smaller machine and be happy with it now, or should I wait another year or two and save money so that when my laptop is considered "old" I can get a blazing fast new one. I guess, in a sense I'm asking is it worth it to pay 1300 now and have a new portable laptop, or in the year or two time I wait and save, will the super machines that are out again obliterate and outmode the already fast computers of today.. I don't want to wait a year or two if we're really only talking gradual incremental differences. Any and all opinions are appreciated!!!
