<human>: Give me the gist of the text in a nutshell

Long story short, I work in IT and got a new job at a company in another state.  Informed old company that I am leaving in two weeks today and they told me since I signed a non-compete agreement that I cannot work for any other IT company.  Can they legally do anything to me?

**More info:**  This company is small company (5 employees) and takes things very personal which I expected.  I was very professional and to the point with my two week notice/resignation.  They started throwing the legalities at me when I would not tell them who I was leaving to work for.  They stated that any job I would get in the IT field was considered competing with them and I legally had to inform them right now who and where I was going to work for.  My understanding is a non-compete agreement is that I cannot sell IT/Networking products to their customers which I will be far from doing (I am a technical support person not a sales person)
<bot>: Quitting job they are personally upset and want to use a non compete I signed to prevent me from leaving/taking new job.
