Rather indifferent towards them to be honest. I think I used more of their floppy drives at one point than anything else they've made.
There aren't many brands I've had a deep interest in to be honest, I always evaluate my options and look at what best suits my needs. One of the few things I have ever bought simply because I 'wanted it' was my NAD integrated amp. I was drawn to them ever since I first saw some NAD components when I was a kid. Would I buy another NAD amp? Absolutely, but if/when I come to that I would definitely survey the alternatives and make sure any new component would provide the necessary performance. If NAD proved to not have what I needed or didn't perform (assuming I was buying a new amp) I'd go with something else.
