Happily, there are a number of companies in the music-tech space who go above and beyond the call of duty like this, but CW is absolutely one of them and it's not just Noel. I've had various bakers chime in here about a problem, send me tentative fixes via PM to get things sorted, that kind of thing - often without me even having to go through actual support channels, which I have hardly ever needed to do.
One of the realities of this business is that for the size of the market there are a lot of people and companies competing to provide the products and services we need, so the pressure is on to make a high level of personal service part of the package, as well as (of course) technical innovation. The smallish scale of the market makes this possible, but also necessary; it's a happy thing for us users, even if the profit ceiling is likely rather low for the companies competing for our disposable income...
However, as has been remarked before, this is not really the business to be in if maximum profit for minimum effort is your main concern; one often has the impression that a product like Sonar, or any number of others in the market, is as much a labour of love as a product competing in a marketplace... and since we musicians are in a similar predicament, we tend to recognise this and reward it with our loyalty. It's not surprising, to me at least, that CW's attitude, baked (as John points out) into the DNA of the company early on, has resulted in the remarkable community of loyal users this forum represents.
Plus, more than a few of us are eccentric quirky weirdos, which keeps things interesting!
