The director of pricing was a tad upset, but she told me that it was because she was hoping to get me transferred to her team eventually -- I was on loan to her temporarily to work out some performance problems.
In one sense I feel bad for the coworkers that I'm leaving stranded, but mostly I just feel... relieved.
Amusing: I started to explain my changes for a new project to a coworker yesterday... when I asked him this morning if he had looked at it at all and he gave me a questioning look I informed him that I had put in notice. He laughed and said that he was about to (in a few days) as well. (Sucks for the department, but they'll get over it)
Also, I bought some CDs today, for the first time in a really really long time... R.E.M. and Styx
