Each person's experience becomes their reality. Those who are experiencing issues make comments referring to the FM9 being unusable, unstable and support laughable. A majority of users do not appear to have these problems and are called fanboys when they respond that they have not experienced any of the stated issues. It's not defending a product nor is it piling on someone being critical.
This is the beta process; someone reports a problem, others try to replicate it and post their experience. Most cases turn out to be user error or something in their setup (monitors, interface, computer etc...) that causes the issue. Other times there is an issue and it gets addressed once it's shown to be one that can be replicated. As far as releasing a more stable beta, with only a handful of official beta testers it's unreasonable to expect every possible setup or scenario to be tested. The forum appears to be an extension of the beta testing process, seeing how it works on even more setups.
On one here is obligated to update to a beta. If you have the time to run it through the paces with your setup and report your findings, or if you understand that some things may go wrong, great. If you update to a beta thinking that you probably won't have any issues, that's completely on you if you do experience problems. It's a Beta. There has never been any guarantee or reassurance that nothing will go wrong with a beta.
Those who continue to worry about things not working properly in beta releases should really wait until the official firmware is released at fractalaudio.com. Even some final releases for other devices posted to the forum have had bugs to address before they make it to the website.
