Not sure how eBay know I'm a student, albeit part-time, but maybe they just blasted this out to everybody. Nevertheless, shows the perception (and maybe reality) of undergrads. The email included links to things that presumably students want, and it's an ordered list:
1. Laptops
2. Backpacks
3. Cell Phones
4. Sneakers
5. iPods
6. Jeans
7. Xbox 360
8. Shirts
9. Textbooks
10. PC Components
Hint: one of those items is actually directly related to going back to school, and another is handy for containing the first. Call me old-fashioned, but I don't see how buying things for an Xbox 360 has anything at all with actual schooling.
And yes, I fully understand the need for hobbies outside of school that aren't competitive drinking, but don't you need those hobbies when you're not in school too? Stupid marketing.
