NeXT was far, far more mature as an OS than BeOS. For years, people had been shipping mission-critical custom software on NeXT.
You had Improv, which when Lotus killed it, was cloned into Quantrix which is still sold today to financial modelers.
You had the McCaw Cellular custom app (don't know what it was called) that allowed them to grow - they later became Cingular, then ATT Wireless. William Morris Agency, Booz Allen Hamilton (big consulting firm), etc. all had custom apps that they used under NeXT.
In contrast, BeOS had a few small desktop apps and some other cool demos.
