For a pre-release package......the fact that there were no significant problems is excellent news. For those who are focusing on the fact that there were some insignificant problems, remember that the company's plan is to release a beta version of the distribution in May, and the shrinkwrap version in June. We're at the end of February and already they appear to have a stable product. They still have over 2 months before the beta release. At this stage of the game, most software development projects are faced with serious defects with which to deal.
Those who have worked in software development will recognize that the prognosis is excellent, assuming that the event was not staged to mask any major problems (which would be very difficult to do in a gaming environment since games are among the most demanding applications on both hardware and O/S).
This is my humble opinion and I encourage all investors to do their own DD.
