Since the MFT update, which came right before I bought my ST2, I have had no issues. Well ok...I had one issue but that was due to the screen / entire unit actually being faulty and just needing to be replaced completely.
After replacement, the system has worked flawlessly.
The only thing that annoys me is the randomly scheduled "Performing system maintenance" job that runs. It seems to happen at random times...no rhyme or reason as to when it happens....also wonder what the hell its doing when it runs this.
