Obviously trivial, but..

After lucas becomes a skull, he gets around $20,000 deposited into his bank account. Later on in the movie, we see lucas typing something on a TYPEWRITER. Yes, it's a movie, and movies are unrealistic. However:

1) I don't care how poor you are, if you can afford to be at college (regardless of scholarship) you should be able to afford some sort of computer.

2) If i received $20,000 for free and I was using a typewriter in college, the first thing I would do is buy a computer.

Like I said, obviously trivial, but it's just something I noticed.
