The key there is the couple of years ago. Before about NB 6.1, I think it was(i.e. around 2007), NB was actually pretty slow and buggy. As the NB 6.x cycle has progressed, however, they have made drastic improvements to the whole platform, including adding a pretty darn functional UI editor. Given that, it may just be worth giving it another try. YMMV, of course.
