I have a Pogoplug and software versino 2.5.5, and I also sometimes access it from my Android phone.  I have read a lot of unsatisfied people that don't like the new software.  I believe that you cannot stream with the new software, but have to pay for some subscription to do that. I am a little hesitant to upgrade because everything seems to finally be working fine the way it is.  If it ain't broken...

My questions is:  What are the pros and cons of the newer version software?  Is it worth it to upgrade?
