I'll echo that, as a former vB owner going back about the same time as Mike, it felt a little like a bad breakup at first, then I played with the 24hr demo and was instantly taken aback by how IPB gets the details right, and understands a user and an admin. Nothing's perfect, but IPBs attention to detail, communication with the customers and belief in providing a quality product at a more than reasonable price, its a real pleasure to see that kind of commitment.
Something that I think a lot of other companies could learn from, by no means has IPS' road been without its bumps but they've come out of it with a truly stellar attitude and direction that will only serve to benefit the company, as well as its customers.
