The idea of running a beta is to catch problems with the product before it ships to the paying public. I have every confidence that Castle will (or maybe has) resolve (d) the issues but it leaves a very bad taste in your mouth. Lack of confidence in the product...until the Rev 2.0 units come out. Maybe not all of the first batch are bad or have a problem but who knows when a first batch MMM will die, maybe it will be in the first 5 minutes or maybe it will be as you round the last corner on your way to a victory...then it puffs and you DNF...not fun.
