Having your own computer in college is a must if you are looking for convenience. The library is equipped with lots of great computers, but going to the library, waiting for a computer, and getting distracted by the hundreds of semi-familiar faces wastes precious time that you will have to make up for later. It is starting to become a bigger trend to see people typing their notes on their laptops in class, but most people still use the library for quick email checks and especially for printing.
We are the digital generation, and professors are catching on to that. A full-time student will be taking courses that, more often than not, rely heavily on the Internet or other computer-based conveniences. You can get through many a class without buying the overpriced textbook, but you cannot make it through college without a computer.
