Oh Bother

Okay, my coffee house study idea didn't work too well. I did get my caramel apple cider and lemon poppyseed for free since their credit card machine wasn't working, however. The problem was that people kept coming into the coffee shop to TALK instead of study. It was soo freaking loud. So, anyway, I am back at home studying where I know the wi-fi is free and the only talking I hear is an occassional cat's meow. Home sweet home.

I am already tired of studying. This is what I have learned so far:

Next, I am on to Devaraj and Kohli 2003 and am going to see how IT Usage is the missing link between IT investments and IT Payoff. Fun, fun.
