Let me give you an answer from my experience in the last three and a half years:
In 2006 and 2007 I had a lot of positives as I told friends and others from PTSC. In January 2008 and for all in April 2008 those positives vanished more and more because it got obvious the MMP had serious problems and new revenue sources were far away.
So to answer your question what is positive about PTSC:
I'm not sure what is positive today and tomorrow.
And the reason is very simple: the company doesn't tell me, they are refusing to speak about the main revenue source and they don't give any reliable outlook to the future of the other businesses (because it's secret again!!!).
So I have to return the question to you: What do you see as a positive what IS NOT based on speculation and hope but on facts provided by the company?
