I find it interesting that a lot of B2 owners seem to enjoy the occasional challenges and finding fixes for them. Even more interesting, if only to me, I think I've become one of those people. Before I got my B2 I wasn't sure, purely based on what I read, if it's a fully finished product or a work in progress. I went ahead because of the company's clear commitment to support and continuous improvement.

It's nice to be part of that, but I understand others may have a different experience.
