By the time your 13.3" MBP arrives, 2 weeks or so still in the future, you will have gone back and forth a dozen more times here, agonizing over all of the pros and cons, and somewhere along the way you'll be on the verge of receiving the 13.3" and go to the Apple refurb store and they'll be out of 16" MBPs, or they won't have one that is configured right for you, and so it will be a whole new set of problems, and then finally you'll receive the 13.3" and it will be so doggone nice, beautiful new computer fresh out of the box, that new computer smell, everything is so great, you'll get it plugged in and start to use it, and all thoughts of anything else will evaporate as if they never existed . . .
