No way should you wait for Black Friday.
First, it's not reasonable to think a college student can be successful without a computer for 3/4 of the semester. Second, those Black Friday deals -- IF you're one of the few who'll actually get one -- tend to be on stripped-down models.
Also, be careful of the school-sold computers. A budget-minded friend of mine told me that she considered the computer offered by her freshman son's college (and it did sound nice to have it picked, waiting in his dorm room) . . . but when she compared it to the same computer at
Best Buy, she found that the school was selling it for almost TWICE THE PRICE.
Incidentally, I suggest that you buy two more things to go with your son's laptop:
1. A warranty. I
rarely buy warranties for things, but a college student's going to haul the computer around in a bookbag, it's going to be left out on the desk around people who are eating/drinking . . . chances of this computer being damaged are fairly good.
2. A laptop lock. At a college information fair, I asked a campus security officer about crime on campus. He said that violent crime is essentially zero, and the #1 crime -- by far -- is laptop theft. Students (or their roommates) leave their laptops out in their dorm rooms while they run down to the laundry room, or they leave their laptops on the library desk while they take a few steps away to retrieve another book . . . and they're gone. Laptop locks only cost about $20.
